109     <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.
110     <br><br>
111     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>.
112     <br><br>
113     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.
114     <br><br>
115     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.

152     <p>Press &lt;TAB&gt; to add additional options.
153     </p>
154     <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.
155     </li></ul>
156     <p>During boot you will be prompted for the keyboard configuration, avoid this by using
157     </p>
158     <ul><li><b>setkmap=kk</b>: which defines the keymap to load where <code>kk</code> (example: <code>setkmap=de</code> for German keyboards)
159     </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>.
160     </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.
161     </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>.
162     </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.

167     <ul><li><b>doload=xxx</b>: loads needed modules, multiple occurrences are permitted (example: <code>doload=3c59x</code>)
168     </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.
169     </li><li><b>nonet</b>: this will disable the network auto detection at startup
170     </li></ul>
171     <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.
172     </li></ul>
173     <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.
174     </li><li><b>nodetect</b>: prevents generic hardware auto-detection. Use this option if you have problems with the hardware auto-detection.
175     </li></ul>
176     <ul><li><b>dostartx</b>: load the X.Org graphical environment.
177     </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.
178     </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>).
179     </li></ul>
180     <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>)
181     </li><li><b>nodmraid</b>: Disable dmraid, for some motherboards with built-in RAID controller.
182     </li><li><b>nomdadm</b>: Disable mdadm, for software RAID.
183     </li></ul>
184     <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, ...

191     <ul><li><b>dodhcp</b>: to request a DHCP server provide network attributes including an IP address, gateway... . otherwise,
192     </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.
193     </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>.
194     </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.
195     </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>.
196     </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.
197     </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.

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).

202     <p>SystemRescueCd provides several options for booting from the network using PXE.
203     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>.

207     </p>
208     <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.
209     </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.
210     </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.
211     </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.

251     <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:
252     <ol>
253     <li>Boot parameters from live-initramfs. You can refer to this <a href="#live-initramfs">manual of live-initramfs</a>.
254     <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.
255     <ul>
256     <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>
257     e.g. ocs_live_run="ocs-live-general"<br>
258     <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>
259     <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>
260     e.g. ocs_live_extra_param="-b -c restoredisk sarge-r5 hda"
261     <li>ocs_live_keymap is for keymap used in Clonezilla live. Man install-keymap for more details.<br>
262     e.g. ocs_live_keymap="NONE" (won't change the default layout)<br>
263     ocs_live_keymap="/usr/share/keymaps/i386/azerty/fr-latin9.kmap.gz" (French keyboard)
264     <li>batch mode or not (yes/no), if no, will run interactively.<br>
265     e.g. ocs_live_batch="no"
266     <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/)
267     e.g. ocs_lang="en_US.UTF-8"
268     <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.
269     <li>ocs_daemonon, ocs_daemonoff, ocs_numlk, ocs_capslk.<br>
270     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.
271     <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.
272     <li>ocs_live_run_tty. This option allows you to specify the tty where $ocs_live_run is run. By default $ocs_live_run is run on /dev/tty1 only. (It was also on /dev/ttyS0 before, but since Clonezilla live >= 1.2.3-22 no more this due to a problem). If you want to use ttyS0, for example, add live-getty and console=ttyS0,38400n81 in the boot parameter.<br>
273     <font color=red>//NOTE//</font><br>
274     <ul>
275     <li>This parameter was added in Clonezilla live 1.2.3-22 or later.
276     <li>If "live-getty console=$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.
277     <li>It's recommended to assign ocs_lang and ocs_live_keymap in the boot parameters too.
278     </ul>
279     <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>
280     ip=eth0,10.0.100.1,255.255.255.0,10.0.100.254,8.8.8.8<br>
281     If more than one network card, you can use ":" to separate them, e.g.:<br>
282     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>
283     <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.
284     </ul>
285     </ol>
286     <hr>
287    
288     With the above options, we have the following examples:
289     <ol>
290     <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>
291     ----------------------------------------<br>
292     label Clonezilla Live<br>
293     MENU LABEL Clonezilla Live<br>
294     MENU DEFAULT<br>
295     kernel vmlinuz1<br>
296     append initrd=initrd1.img boot=live union=aufs noswap noprompt vga=788 fetch=tftp://192.168.120.254/filesystem.squashfs usercrypted=bkuQxLqLRuDW6 ocs_numlk="on" ocs_daemonon="ssh"<br>
297     ----------------------------------------<br>
298    
299     The usercrypted password is created by:<br>
300     echo YOUR_PASSWORD | mkpasswd -s<br>
301     ("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>
302     //NOTE// If you do not assign salt to mkpasswd, the encrypted password will not be the same every time you create it.<br>
303     For more about usercrypted discussion, please check the <a href="http://lists.debian.org/debian-live/2008/10/msg00020.html" target=_blank>here</a>.
304     <br><br>
305     <li>How to put your own binary driver in Clonezilla live without modifying /live/filesystem.squashfs:
306     <ul>
307     <li>Boot clonezilla live
308     <li>Become root by running "sudo su -"
309     <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>
310     cp -r /live/image/lsi /home/partimag
311     <li>cd /home/partimag
312     <li>/opt/drbl/sbin/ocs-live-dev -c -s -i lsi -u lsi -x "ocs_prerun=/live/image/lsi/prep-lsi.sh"
313     <li>/opt/drbl/sbin/ocs-iso -s -i lsi -u lsi -x "ocs_prerun=/live/image/lsi/prep-lsi.sh"
314     <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:
315     <pre>
316     ------------------------
317     #!/bin/bash
318     cp -f /live/image/lsi/megasr.ko /lib/modules/`uname -r`/kernel/drivers/block/
319     chown root.root /lib/modules/`uname -r`/kernel/drivers/block/megasr.ko
320     depmod -a modprobe megasr
321     sleep 1
322     ------------------------
323     </pre>
324     </ul>
325    
326     <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>
327     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>

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