105     <p>Booting a linux system means loading a kernel, which is actually the operating system. Well, this is not exactly true, and it is not the only thing that happens during boot up phase, but it is not my intension to explain it here.
106     <br><br>
107     The kernel is loaded by Isolinux (the CD boot manager), which is able to pass a number of parameters to it, through its configuration file <b>isolinux.cfg</b>.
108     <br><br>
109     These parameters, called boot parameters, are documented by the kernel itself, and can differentiate its behavior dramatically. In our case, each CD (SystemRescueCD and Clonezilla Live) accept a different set of parameters, because they are based on <a href="http://www.gentoo.org/" target="_blank">gentoo</a> and <a href="http://www.debian.org/" target="_blank">debian</a>, respectively.
110     <br><br>
111     While in the splash screen of <b>Clonezilla-SysRescCD</b>, you can edit the boot parameters by pressing TAB. They will be presented to you, and you can add or remove what you want. You must be careful not to change or remove the parameters that are dedicated to the CD itself, as altering them will certainty make it unbootable. When you are done, just press ENTER to boot.

148     <p>Press &lt;TAB&gt; to add additional options.
149     </p>
150     <ul><li><b>docache</b>: causes the CD-ROM will be fully loaded into memory. A slower start but once complete, programs start faster and the CD drive will be released allowing normal access to other CDs. This requires 400MB of memory to cache everything (including the <code>bootdisks</code> and <code>isolinux</code> directories). Add <code>lowmem</code> if you have less that 400MB of memory of to prevent these directories to be copied.
151     </li></ul>
152     <p>During boot you will be prompted for the keyboard configuration, avoid this by using
153     </p>
154     <ul><li><b>setkmap=kk</b>: which defines the keymap to load where <code>kk</code> (example: <code>setkmap=de</code> for German keyboards)
155     </li><li><b>root=/dev/xdnp</b>: the <a href="http://www.sysresccd.org/news/2008/06/05/use-systemrescuecd-to-boot-a-linux-os-from-the-hard-disk/" class="external text" title="http://www.sysresccd.org/news/2008/06/05/use-systemrescuecd-to-boot-a-linux-os-from-the-hard-disk/" rel="nofollow">root=&lt;device&gt; option</a> boots an existing linux system. For example, if you have linux Gentoo installed on <code>/dev/sda6</code>, use <code>rescuecd root=/dev/sda6</code> to start it. Keep in mind that you must use a 64bit kernel if your system is made of 64bit programs. This option works with LVM volumes. Use <code>rescuecd root=/dev/VolGroup00/LogVol00</code>. Support is also provided for <code>root=auto</code>, which scans all the block devices tfor a linux system. The first linux system found will be started. So with <code>root=auto</code> let you start the system installed from the CD-ROM in case you have problem with your boot loader or kernel. It's also possible to specify a partition using its <code>filesystem label</code> or <code>filesystem uuid</code>. If the label of the partition where linux is installed is <code>mylinux</code>, then boot it using <code>rescuecd root=LABEL=mylinux</code>. Similarly <code>root=UUID=b3d3bec5-997a-413e-8449-0d0ec41ccba7</code>. See <a href="http://www.sysresccd.org/news/2008/06/05/use-systemrescuecd-to-boot-a-linux-os-from-the-hard-disk/" class="external text" title="http://www.sysresccd.org/news/2008/06/05/use-systemrescuecd-to-boot-a-linux-os-from-the-hard-disk/" rel="nofollow">more details</a>.
156     </li><li><b>initscript=service:action</b>: This options allows start/stop a service at boot time. For instance if you need the samba service to be started, you can boot with: <code>initscript=samba:start</code>. This does the same thing as <code>/etc/init.d/samba start</code>. Use this option multiple times for different services. All the actions that are supported by an initscript can be used.
157     </li><li><b>backstore=xxx</b>: SystemRescueCd comes with support for the <a href="http://www.sysresccd.org/news/2008/06/29/creating-a-backing-store-to-keep-your-modifications-in-sysresccd/" class="external text" title="http://www.sysresccd.org/news/2008/06/29/creating-a-backing-store-to-keep-your-modifications-in-sysresccd/" rel="nofollow">backing-stores</a>. A backing-store saves all the changes you can make. so that you keep these changes the next time you boot it. By default, sysresccd automatically scan removable devices (eg: USB sticks) at boot time and uses the first backing-store it finds. A backing-store is not mandatory and it the scan fails it will store the files which change in memory. To disable the disks scan at boot time specify <code>backstore=off</code> on the boot command line. If you want to save your backing-store file on an harddisk, boot with <code>backstore=alldev</code> to scan all devices (not just removable devices). The default location for backing-stores file is any file named <code>sysrcd.bs</code> located at the root of a disk which is often an USB stick. Change the path by using <code>backstore=/sysrcd/mybackstore.bs</code>. See <a href="http://www.sysresccd.org/news/2008/06/29/creating-a-backing-store-to-keep-your-modifications-in-sysresccd/" class="external text" title="http://www.sysresccd.org/news/2008/06/29/creating-a-backing-store-to-keep-your-modifications-in-sysresccd/" rel="nofollow">backing-stores</a>.
158     </li><li><b>isoloop=xxx</b>: Grub2 (currently in development: grub-1.98) provides a new feature to boot from an ISO image which is stored from the hard disk. If you put a copy of <code>systemrescuecd-x86-x.y.z.iso</code> on a partition that Grub2 can read then you can boot SystemRescueCd directly from the ISO image stored on your hard drive. This is very convenient if you frequently update SystemRescueCd and you want to boot it directly from Grub2. Grub2 knows what an ISO image is and it will load the kernel image (rescuecd/rescue64) and the initramfs (initram.igz) from the ISO into memory. It will then do its normal job and execute the kernel. The SystemRescueCd init script must then be aware that its <code>sysrcd.dat</code> file is in an ISO and not directly on the partition. For that reason, this <code>isoloop=xxx</code> boot option is required so you must use it in your <code>grub.cfg</code>. This option is only supported in SystemRescueCd-1.4.0 and more recent. This option specifies the path of the ISO image in the partition that grub considers as its root partition. It's important to understand that the path of the ISO image may be different from the path on your linux system. If you have a separate boot partition mounted on <code>/boot</code> and if you copy this ISO image to <code>/boot/sysrcd/systemrescuecd-x86-x.y.z.iso</code> then the option has to be <code>isoloop=/sysrcd/systemrescuecd-x86-x.y.z.iso</code>. This is because the boot partition is what Grub2 will consider as its root partition during the boot process. Please read <a href="http://www.sysresccd.org/Sysresccd-manual-en_Easy_install_SystemRescueCd_on_harddisk#Boot_the_ISO_image_from_the_disk_using_Grub2" title="Sysresccd-manual-en Easy install SystemRescueCd on harddisk">the section about isoloop</a> for more details.

164     </li><li><b>noload=xxx</b>: prevents loading modules, multiple occurrences are permitted (example: <code>noload=3c59x</code>). Use this option if you have a problem when the system loads a particular module.
165     </li><li><b>nonet</b>: this will disable the network auto detection at startup
166     </li></ul>
167     <ul><li><b>scandelay=x</b>: pauses x seconds during the startup to allow slow devices to initialize. This is required when you boot an USB device. A delay of only few seconds should be enough.
168     </li></ul>
169     <ul><li><b>doxdetect</b>: Since version 0.3.5 the auto-configuration is done in X.Org itself, mkxf86config is disabled by default. This option forces the system to run the mkxf86config startup script and to run the hardware auto-detection from this script. Use this option if you have problems with the graphical environment configuration. This option replaces the option <code>noxdetect</code> that was useful in previous versions.
170     </li><li><b>nodetect</b>: prevents generic hardware auto-detection. Use this option if you have problems with the hardware auto-detection.
171     </li></ul>
172     <ul><li><b>dostartx</b>: load the X.Org graphical environment.
173     </li><li><b>forcevesa</b>: Forces X.Org to use the safe VESA driver instead of the best video driver detected for your video card. Use this option if you cannot get the graphical environment working with the default options.
174     </li><li><b>forcevesa=xxx</b>: The <code>startx</code> command will load the <code>Xvesa</code> server instead of <code>Xorg</code>, and use the screen resolution given as parameter (eg: <code>1024x768</code>, <code>1280x1024x32</code>).
175     </li></ul>
176     <ul><li><b>all-generic-ide</b>: In case of problems related to your hard disk, try to enable this option (eg <code>rescuecd all-generic-ide</code>)
177     </li><li><b>nodmraid</b>: Disable dmraid, for some motherboards with built-in RAID controller.
178     </li><li><b>nomdadm</b>: Disable mdadm, for software RAID.
179     </li></ul>
180     <ul><li><b>acpi-off</b> / <b>noapic</b> / <b>irqpool</b>: use these options if you have problem when the kernel boots: if it hangs on a driver or if it crashes, ...

187     <ul><li><b>dodhcp</b>: to request a DHCP server provide network attributes including an IP address, gateway... . otherwise,
188     </li><li><b>ethx=ipaddr/cidr</b>: Sets the static IP address of all the ethernet interfaces on the system. The <code>/cidr</code> extension is optional. For instance, if you use option <code>ethx=192.168.0.1</code> on a machine with two ethernet adapters, both <code>eth0</code> and <code>eth1</code> will be configured with <code>192.168.0.1</code>. You can use the format <code>ethx=10.0.0.1/24</code> (using the cidr notation) if you don't use the default netmask.
189     </li><li><b>eth0=ipaddr/cidr</b>: This option is similar to <code>ethx=ipaddr/cidr</code> but it configures only one interface at a time. To configure the network on a server that has two interfaces, use: <code>eth0=192.168.10.1/24 eth1=192.168.20.1</code>.
190     </li><li><b>dns=ipaddr</b>: Sets the static IP address of the DNS nameserver you want to use to resolve the names. For instance <code>dns=192.168.0.254</code> means that you want to use <code>192.168.0.254</code> as the DNS server.
191     </li><li><b>gateway=ipaddr</b>: Sets the static IP address of the default route on your network. For instance <code>gateway=192.168.0.254</code> means that the computer can connect to a computer outside of the local network via <code>192.168.0.254</code>.
192     </li><li><b>dhcphostname=myhost</b>: Sets the hostname that the DHCP client will send to the DHCP server. This may be required if the default hostname cannot be used with your DHCP configuration. This option has been introduced in SystemRescueCd-1.3.5.
193     </li><li><b>rootpass=123456</b>: Sets the root password of the system running on the livecd to <code>1234</code>. That way you can connect from the network and ssh on the livecd and give <code>123456</code> password as the root password.
194     </li><li><b>vncserver=x:123456</b>: The <a href="http://www.sysresccd.org/news/2008/04/12/use-systemrescuecd-remotely-with-vnc-server/" class="external text" title="http://www.sysresccd.org/news/2008/04/12/use-systemrescuecd-remotely-with-vnc-server/" rel="nofollow">vncserver boot option</a> has been introduced in SystemRescueCd-1.0.2. This options forces the system to configure the VNC-server and to start it automatically at boot time. You have to replace <code>x</code> with the number of displays you want, and <code>123456</code> with your password The password must be between 5 and 8 characters, else the boot option will be ignored. In other words the <code>vncserver=2:MyPaSsWd</code> option will give you access to two displays (display=1 on tcp/5901 and display=2 on tcp/5902). Display 0 is reserved for X.Org since SystemRescueCd-1.1.0.

You need SystemRescueCd-1.1.0 or newer to do that. Here is how you can specify which interface is using which mac address on a machine with two network interfaces: <code>nameif=eth0!00:0C:29:57:D0:6E,eth1!00:0C:29:57:D0:64</code>. Be careful, you have to respect the separator (comma between the interfaces and exclamation marks between the name and the mac address).

198     <p>SystemRescueCd provides several options for booting from the network using PXE.
199     These options can be combined with other network boot options such as <code>ethx</code> (cf previous section). See <a href="http://www.sysresccd.org/Sysresccd-manual-en_PXE_network_booting" class="external text" title="http://www.sysresccd.org/Sysresccd-manual-en_PXE_network_booting" rel="nofollow">PXE network booting</a> to get a global overview of SystemRescueCd and PXE and <a href="http://www.sysresccd.org/Sysresccd-manual-en_Manage_remote_windows_linux_servers_using_SystemRescueCd" class="external text" title="http://www.sysresccd.org/Sysresccd-manual-en_Manage_remote_windows_linux_servers_using_SystemRescueCd" rel="nofollow">Manage remote servers using PXE</a>.

201     </p><p>The third stage of the PXE boot process acquires the root files system.
202     </p><p>Several protocols are available.
203     </p>
204     <ul><li><b>netboot=</b>tftp<b>://ip/path/sysrcd.dat</b>: from a TFTP server. The filesystem is loaded into memory. As a consequence computers with less than 400MB of memory won't be able to boot this way. The system will continue to work if the network is disconnected after the boot process.
205     </li><li><b>netboot=</b>http<b>://ip:port/path/sysrcd.dat</b>: from a Web server. The file system is loaded into memory. Computers with smaller memory won't be able to boot this way. The the system continues to work if the network is disconnected after the boot process.
206     </li><li><b>netboot=</b>nfs<b>://ip:/path</b>: mount an NFSv3 directory. The NFS url must be the path of the directory that contains <code>sysrcd.dat</code>. Only NFSv3 can be used, NFSv4 is not supported. NFS it allows computers with smaller memory to boot SystemRescueCd from the network. After the boot process, the connection is required or you will loose the access to the root file system.
207     </li><li><b>netboot=</b>nbd<b>://ip:port</b>: connect to an NBD server configured with <code>sysrcd.dat</code> on ip:port. NBD is easier to configure than NFS (only one TCP port involved) and it allows computers with smaller memort to boot SystemRescueCd from the network. After the boot process, the connection is required the access to the root system.

247     <div class="otherpage">Clonezilla live is based on <a href="http://wiki.debian.org/DebianLive/" target=_blank>Debian live</a> with clonezilla installed. Therefore there are 2 kinds of boot parameters:
248     <ol>
249     <li>Boot parameters from live-initramfs. You can refer to this <a href="#live-initramfs">manual of live-initramfs</a>.
250     <li>Boot parameters specially for Clonezilla. All of them are named as "ocs_*", e.g. ocs_live_run, ocs_live_extra_param, ocs_live_batch, ocs_lang.
251     <ul>
252     <li>ocs_live_run is the main program to run in Clonezilla live to save or restore. or other command. Available program: ocs-live-general, ocs-live-restore or any command you write. Use the Absolute path in Clonezilla live.<br>
253     e.g. ocs_live_run="ocs-live-general"<br>
254     <font color="red">//NOTE// You might have to use "sudo" command inside your own script, or you can assign it like: ocs_live_run="sudo bash /my-clonezilla"</font><br>
255     <li>ocs_live_extra_param will be used only when ocs_live_run=ocs-live-restore (not for ocs-live-general or any other), then it will be passed to ocs-sr. Therefore these parameters are actually those of ocs-sr.<br>
256     e.g. ocs_live_extra_param="-b -c restoredisk sarge-r5 hda"
257     <li>ocs_live_keymap is for keymap used in Clonezilla live. Man install-keymap for more details.<br>
258     e.g. ocs_live_keymap="NONE" (won't change the default layout)<br>
259     ocs_live_keymap="/usr/share/keymaps/i386/azerty/fr-latin9.kmap.gz" (French keyboard)
260     <li>batch mode or not (yes/no), if no, will run interactively.<br>
261     e.g. ocs_live_batch="no"
262     <li>ocs_lang is the language used in Clonezilla live. Available value: en_US.UTF-8, zh_TW.UTF-8... (see $DRBL_SCRIPT_PATH/lang/bash/)
263     e.g. ocs_lang="en_US.UTF-8"
264     <li>ocs_debug (or ocs-debug) is for you to enter command line prompt before any clonezilla-related action is run. This is easier for you to debug.
265     <li>ocs_daemonon, ocs_daemonoff, ocs_numlk, ocs_capslk.<br>
266     Ex. for the first 2 parameters, ocs_daemonon="ssh", then ssh service will be turned on when booting. For the last 2 parameters, use "on" or "off", e.g. ocs_numlk=on to turn on numberlock when booting.
267     <li>ocs_prerun, ocs_prerun1, ocs_prerun2... is for you to run a shell script before Clonezilla is started. E.g. ocs_prerun="/live/image/myscript.sh". If you have more commands to run, you can assign them in the order: ocs_prerun=..., ocs_prerun1=..., ocs_prerun2=.... If more than 10 parameters, remember to use ocs_prerun01, ocs_prerun02..., ocs_prerun11 to make it in order.
268     <li>ocs_live_run_tty. This option allows you to specify the tty where $ocs_live_run is run. By default $ocs_live_run is run on /dev/tty1 only. (It was also on /dev/ttyS0 before, but since Clonezilla live >= 1.2.3-22 no more this due to a problem). If you want to use ttyS0, for example, add live-getty and console=ttyS0,38400n81 in the boot parameter.<br>
269     <font color=red>//NOTE//</font><br>
270     <ul>
271     <li>This parameter was added in Clonezilla live 1.2.3-22 or later.
272     <li>If "live-getty console=$tty,38400n81" are assigned in the boot parameters, ocs_live_run_tty will honor $tty, even other value is assigned to ocs_live_run_tty in boot parameter.
273     <li>It's recommended to assign ocs_lang and ocs_live_keymap in the boot parameters too.
274     </ul>
275     <li>ip, this option allows you to specify the network parameters for network card. In Clonezilla live a patched live-initramfs is used, which is different from the original live-initramfs so that you can assign DNS server, too. Its format is: ip=ethernet port,IP address, netmask, gateway, DNS. E.g. If you want to assing eth0 with IP address 10.0.100.1, netmask 255.255.255.0, gateway 10.0.100.254, DNS server 8.8.8.8, you can assign the following in the boot parameter:<br>
276     ip=eth0,10.0.100.1,255.255.255.0,10.0.100.254,8.8.8.8<br>
277     If more than one network card, you can use ":" to separate them, e.g.:<br>
278     ip=eth0,10.0.100.1,255.255.255.0,10.0.100.254,8.8.8.8:eth1,192.168.120.1,255.255.255.0,192.168.120.254,,<br>
279     <li>Besides, "live-netdev" (yes, not ocs_live_netdev) can be used when using PXE booting, you can force to assign the network device to get filesystem.squashfs. This is useful when there are two or more NICs are linked. E.g. live-netdev="eth1" allows you to force the live-initramfs to use eth1 to fetch the root file system filesystem.squashfs.
280     </ul>
281     </ol>
282     <hr>
283    
284     With the above options, we have the following examples:
285     <ol>
286     <li>A PXE config example for you to boot Clonezilla live via PXE, and ssh service is on, the password of account "user" is assigned:<br>
287     ----------------------------------------<br>
288     label Clonezilla Live<br>
289     MENU LABEL Clonezilla Live<br>
290     MENU DEFAULT<br>

293     ----------------------------------------<br>
294    
295     The usercrypted password is created by:<br>
296     echo YOUR_PASSWORD | mkpasswd -s<br>
297     ("mkpasswd" is from package "whois" in Debian or Ubuntu. Check your GNU/Linux to see which package provides this command if you are not using Debian or Ubuntu. Replace YOUR_PASSWORD with your plain text password, and remember do not put any " in the boot parameters of live-initramfs (while it's ok for those ocs_* boot parameters), i.e. do NOT use something like usercrypted="bkuQxLqLRuDW6").<br>
298     //NOTE// If you do not assign salt to mkpasswd, the encrypted password will not be the same every time you create it.<br>
299     For more about usercrypted discussion, please check the <a href="http://lists.debian.org/debian-live/2008/10/msg00020.html" target=_blank>here</a>.
300     <br><br>
301     <li>How to put your own binary driver in Clonezilla live without modifying /live/filesystem.squashfs:
302     <ul>
303     <li>Boot clonezilla live
304     <li>Become root by running "sudo su -"
305     <li>Copy the dir lsi, which contains a precompiled kernel module matching the running kernel in Clonezilla live and a script to run it, to a working dir, e.g.: <br>
306     cp -r /live/image/lsi /home/partimag
307     <li>cd /home/partimag
308     <li>/opt/drbl/sbin/ocs-live-dev -c -s -i lsi -u lsi -x "ocs_prerun=/live/image/lsi/prep-lsi.sh"
309     <li>/opt/drbl/sbin/ocs-iso -s -i lsi -u lsi -x "ocs_prerun=/live/image/lsi/prep-lsi.sh"
310     <li>///NOTE/// In this example, the 2 files in dir lsi are: megasr.ko (the binary driver) and prep-lsi.sh. The contents of prep-lsi.sh:
311     <pre>
312     ------------------------
313     #!/bin/bash
314     cp -f /live/image/lsi/megasr.ko /lib/modules/`uname -r`/kernel/drivers/block/
315     chown root.root /lib/modules/`uname -r`/kernel/drivers/block/megasr.ko
316     depmod -a modprobe megasr
317     sleep 1
318     ------------------------
319     </pre>
320     </ul>
321    
322     <li>To put your customized script with a PXE version of Clonezilla live (You have to use Clonezilla live version 1.2.2-2 or later):<br>
323     In this example, we assume (1) The IP address of your PXE server is 192.168.120.254, (2) the customized script (custom-ocs-2) is put on your PXE server's tftpd root dir (E.g. On DRBL server, the path is /tftpboot/nbi_img/. It might be different in your case if you are not use DRBL server as a PXE server).<br>

377    
378     Name
379     ----
380     live-initramfs - Debian Live initramfs hook
381    
382     Synopsis
383     --------
384     BOOT=live
385    
386     as kernel parameter at boot prompt.
387    
388     Description
389     -----------
390    
391     live-initramfs is a hook for the initramfs-tools, used to generate a initramfs
392     capable to boot live systems, such as those created by *live-helper*(7).
393     This includes the Debian Live isos, netboot tarballs, and usb stick images.
394    
395     At boot time it will look for a (read-only) media containing a "/live"
396     directory where a root filesystems (often a compressed filesystem image like
397     squashfs) is stored. If found, it will create a writable environment, using
398     aufs, for Debian like systems to boot from.
399    
400     You probably do not want to install this package onto a non-live system,
401     although it will do no harm.
402    
403     live-initramfs is a fork of link:http://packages.ubuntu.com/casper/[casper].
404     casper was originally written by Tollef Fog Heen &lt;tfheen@canonical.com&gt;
405     and Matt Zimmerman &lt;mdz@canonical.com&gt;.
406    
407     Boot options
408     ------------
409    
410     Here is the complete list of recognized boot parameters by live-initramfs.
411    
412     access=*ACCESS*::
413    
414     Set the accessibility level for physically or visually impared users. ACCESS
415     must be one of v1, v2, v3, m1, or m2. v1=lesser visual impairment, v2=moderate
416     visual impairment, v3=blindness, m1=minor motor difficulties, m2=moderate motor
417     difficulties.
418    
419     console=*TTY,SPEED*::
420    
421     Set the default console to be used with the "live-getty" option. Example:
422     "console=ttyS0,115200"
423    
424     debug::
425    
426     Makes initramfs boot process more verbose.
427    
428     fetch=*URL*::
429    
430     Another form of netboot by downloading a squashfs image from a given url,
431     copying to ram and booting it.
432    
433     hostname=*HOSTNAME*, username=*USER*, userfullname=*USERFULLNAME*::
434    
435     Those parameters lets you override values read from the config file.
436    
437     ignore_uuid
438    
439     Do not check that any UUID embedded in the initramfs matches the discovered
440     medium. live-initramfs may be told to generate a UUID by setting
441     LIVE_GENERATE_UUID=1 when building the initramfs.
442    
443     integrity-check::
444    
445     If specified, an MD5 sum is calculated on the live media during boot and
446     compared to the value found in md5sum.txt found in the root directory of the
447     live media.
448    
449     ip=**[CLIENT_IP]:[SERVER_IP]:[GATEWAY_IP]:[NETMASK]:[HOSTNAME]:[DEVICE]:[AUTOCONF]
450     [,[CLIENT_IP]:[SERVER_IP]:[GATEWAY_IP]:[NETMASK]:[HOSTNAME]:[DEVICE]:[AUTOCONF]]***::
451    
452     Let you specify the name(s) and the options of the interface(s) that should be
453     configured at boot time. Do not specify this if you want to use dhcp (default).
454     It will be changed in a future release to mimick official kernel boot param
455     specification (e.g. ip=10.0.0.1::10.0.0.254:255.255.255.0::eth0,:::::eth1:dhcp).
456    
457     ip[=**frommedia**]::
458    
459     If this variable is set, dhcp and static configuration are just skipped and the
460     system will use the (must be) media-preconfigured /etc/network/interfaces
461     instead.
462    
463     {keyb|kbd-chooser/method}=**KEYBOARD**, {klayout|console-setup/layoutcode}=**LAYOUT**,
464     {kvariant|console-setup/variantcode}=**VARIANT**,
465     {kmodel|console-setup/modelcode}=**CODE**, koptions=**OPTIONS**::
466    
467     Configure the running keyboard as specified, if this one misses live-initramfs
468     behaves as if "keyb=us" was specified. It will be interfered from "locale=" if
469     locale is only 2 lowecase letters as a special case. You could also specify
470     console layout, variant, code, and options (no defaults).
471    
472     live-getty::
473    
474     This changes the auto-login on virtual terminals to use the (experimental)
475     live-getty code. With this option set the standard kernel argument "console=" is
476     parsed and if a serial console is specified then live-getty is used to autologin
477     on the serial console.
478    
479     {live-media|bootfrom}=**DEVICE**::
480    
481     If you specify one of this two equivalent forms, live-initramfs will first try
482     to find this device for the "/live" directory where the read-only root
483     filesystem should reside. If it did not find something usable, the normal scan
484     for block devices is performed.
485    
486     {live-media-encryption|encryption}=**TYPE**::
487    
488     live-initramfs will mount the encrypted rootfs TYPE, asking the passphrase,
489     useful to build paranoid live systems :-). TYPE supported so far are "aes" for
490     loop-aes encryption type.
491    
492     live-media-offset=**BYTES**::
493    
494     This way you could tell live-initramfs that your image starts at offset BYTES in
495     the above specified or autodiscovered device, this could be useful to hide the
496     Debian Live iso or image inside another iso or image, to create "clean" images.
497    
498     live-media-path=**PATH**::
499    
500     Sets the path to the live filesystem on the medium. By default, it is set to
501     '/live' and you should not change that unless you have customized your media
502     accordingly.
503    
504     live-media-timeout=**SECONDS**::
505    
506     Set the timeout in seconds for the device specified by "live-media=" to become
507     ready before giving up.
508    
509     {locale|debian-installer/locale}=**LOCALE**::
510    
511     Configure the running locale as specified, if not present the live-media rootfs
512     configured locale will be used and if also this one misses live-initramfs behave
513     as "locale=en_US.UTF-8" was specified. If only 2 lowercase letter are specified
514     (like "it"), the "maybe wanted" locale is generated (like en:EN.UTF-8), in this
515     case if also "keyb=" is unspecified is set with those 2 lowercase letters
516     (keyb=us). Beside that facility, only UTF8 locales are supported by
517     live-initramfs.
518    
519     module=**NAME**::
520    
521     Instead of using the default optional file "filesystem.module" (see below)
522     another file could be specified without the extension ".module"; it should be
523     placed on "/live" directory of the live medium.
524    
525     netboot[=**nfs**|**cifs**]::
526    
527     This tells live-initramfs to perform a network mount. The parameter "nfsroot="
528     (with optional "nfsopts="), should specify where is the location of the root
529     filesystem. With no args, will try cifs first, and if it fails nfs.
530    
531     nfsopts=::
532    
533     This lets you specify custom nfs options.
534    
535     noautologin::
536    
537     This parameter disables the automatic terminal login only, not touching gdk/kdm.
538    
539     noxautologin::
540    
541     This parameter disables the automatic login of gdm/kdm only, not touching
542     terminals.
543    
544     nofastboot::
545    
546     This parameter disables the default disabling of filesystem checks in
547     /etc/fstab. If you have static filesystems on your harddisk and you want them to
548     be checked at boot time, use this parameter, otherwise they are skipped.
549    
550     nopersistent::
551    
552     disables the "persistent" feature, useful if the bootloader (like syslinux) has
553     been installed with persistent enabled.
554    
555     noprompt
556    
557     Do not prompt to eject the CD on reboot.
558    
559     nosudo::
560    
561     This parameter disables the automatic configuration of sudo.
562    
563     swapon::
564    
565     This parameter enables usage of local swap partitions.
566    
567     nouser::
568    
569     This parameter disables the creation of the default user completely.
570    
571     noxautoconfig::
572    
573     This parameter disables Xorg auto-reconfiguration at boot time. This is valuable
574     if you either do the detection on your own, or, if you want to ship a custom,
575     premade xorg.conf in your live system.
576    
577     persistent[=nofiles]::
578    
579     live-initramfs will look for persistent and snapshot partitions or files labeled
580     "live-rw", "home-rw", and files called "live-sn*", "home-sn*" and will try to,
581     in order: mount as /cow the first, mount the second in /home, and just copy the
582     contents of the latter in appropriate locations (snapshots). Snapshots will be
583     tried to be updated on reboot/shutdown. Look at live-snapshot(1) for more
584     informations. If "nofiles" is specified, only filesystems with matching labels
585     will be searched; no filesystems will be traversed looking for archives or image
586     files. This results in shorter boot times.
587    
588     {preseed/file|file}=**FILE**::
589    
590     A path to a file present on the rootfs could be used to preseed debconf
591     database.
592    
593     package/question=**VALUE**::
594    
595     All debian installed packages could be preseeded from command-line that way,
596     beware of blanks spaces, they will interfere with parsing, use a preseed file in
597     this case.
598    
599     quickreboot::
600    
601     This option causes live-initramfs to reboot without attempting to eject the
602     media and without asking the user to remove the boot media.
603    
604     showmounts::
605    
606     This parameter will make live-initramfs to show on "/" the ro filesystems
607     (mostly compressed) on "/live". This is not enabled by default because could
608     lead to problems by applications like "mono" which store binary paths on
609     installation.
610    
611     textonly
612    
613     Start up to text-mode shell prompts, disabling the graphical user interface.
614    
615     timezone=**TIMEZONE**::
616    
617     By default, timezone is set to UTC. Using the timezone parameter, you can set it
618     to your local zone, e.g. Europe/Zurich.
619    
620     todisk=**DEVICE**::
621    
622     Adding this parameter, live-initramfs will try to copy the entire read-only
623     media to the specified device before mounting the root filesystem. It probably
624     needs a lot of free space. Subsequent boots should then skip this step and just
625     specify the "live-media=DEVICE" boot parameter with the same DEVICE used this
626     time.
627    
628     toram::
629    
630     Adding this parameter, live-initramfs will try to copy the whole read-only media
631     to the computer's RAM before mounting the root filesystem. This could need a lot
632     of ram, according to the space used by the read-only media.
633    
634     union=**aufs**|**unionfs**::
635    
636     By default, live-initramfs uses aufs. With this parameter, you can switch to
637     unionfs.
638    
639     utc=**yes**|**no**::
640    
641     By default, Debian systems do assume that the hardware clock is set to UTC. You
642     can change or explicitly set it with this parameter.
643    
644     xdebconf::
645    
646     Uses xdebconfigurator, if present on the rootfs, to configure X instead of the
647     standard procedure (experimental).
648    
649     xvideomode=**RESOLUTION**::
650    
651     Doesn't do xorg autodetection, but enforces a given resolution.
652    
653     Files
654     -----
655    
656     /etc/live.conf
657    
658     Some variables can be configured via this config file (inside the live system).
659    
660     /live/filesystem.module
661    
662     This optional file (inside the live media) contains a list of white-space or
663     carriage-return-separated file names corresponding to disk images in the "/live"
664     directory. If this file exists, only images listed here will be merged into the
665     root aufs, and they will be loaded in the order listed here. The first entry
666     in this file will be the "lowest" point in the aufs, and the last file in
667     this list will be on the "top" of the aufs, directly below /cow. Without
668     this file, any images in the "/live" directory are loaded in alphanumeric order.
669    
670     /etc/live-persistence.binds
671    
672     This optional file (which resides in the rootfs system, not in the live media)
673     is used as a list of directories which not need be persistent: ie. their
674     content does not need to survive reboots when using the persistence features.
675    
676     This saves expensive writes and speeds up operations on volatile data such as
677     web caches and temporary files (like e.g. /tmp and .mozilla) which are
678     regenerated each time. This is achieved by bind mounting each listed directory
679     with a tmpfs on the original path.
