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.
116     </p>

131     <!--empty-line-->
132     <p>The kernel used is <b>rescuecd</b>, and anything after the word <b>append</b> is a boot parameter.<br><br>
133     <!--empty-line-->
134     Available kernels (boot images):</p>
135    
136     <ul class="otherpage" style="padding: 0px 10px 20px 40px">
137     <li><b>rescuecd</b> This is the default choice for 32bits systems, with Framebuffer disabled, best choice.</li>
138     <li><b>altker32</b> This is an alternative kernel for 32bits systems. Boot with this kernel in case you have problems with rescuecd. altker32 was named vmlinuz2 in versions prior to SystemRescueCd-1.0.0.</li>
139     <li><b>rescue64</b> This is the default 64 bits kernel. Use it if you want to chroot to a 64bits linux system installed on your hard disk, or if you have to run 64 bits programs. This kernel is able to boot SystemRescueCd from the cdrom with 32bits programs, and it required a processor with 64bits instructions (amd64 / em64t).</li>
140     <li><b>altker64</b> This is an alternative kernel for 64bits systems. Boot with this kernel in case you have problems with rescue64. Only available from SystemRescueCd-1.0.0 and newer.</li>
141     </ul>
142    
143    
144     <p><br>The boot parameters you can use are:</p>
145    
146    
147     <div class="otherpage">
148     <p><b>General boot options</b></p>
149    
150     <ul><li><b>setkmap=xx</b>: if you don't want to be asked for the keymap, you can choose which keymap to load automatically. Replace <code>xx</code> with your keymap (for example: <code>setkmap=de</code> for german keyboards)
151     </li><li><b>docache</b>: this option is very useful if you need to insert another disc in the CD drive after booting. The CD-ROM will be fully loaded into memory, and you will be able to remove the disc from the drive. The <code>docache</code> option requires 400MB of memory if you want to cache everything (including the <code>bootdisks</code> and <code>isolinux</code> directories). You can add the <code>lowmem</code> option if you have less that 400MB of memory of to prevent these directories to be copied into memory.
152     </li><li><b>root=xxx</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> lets you boot an existing linux system. For example, if you have a linux gentoo installed on <code>/dev/sda6</code>, you can type <code>rescuecd root=/dev/sda6</code> and Gentoo Linux will be started instead of the system that is on the CD-ROM. Keep in mind that you must use a 64bits kernel if your system is made of 64bits programs. For instance, you can boot a 64bits linux system installed on /dev/sda6 with <code>rescue64 root=/dev/sda6</code>. From SystemRescueCd-1.0.4, this option works with LVM disks, so you can write something like <code>rescuecd root=/dev/VolGroup00/LogVol00</code>. SystemRescueCd-1.0.4 and newer versions also supports <code>root=auto</code>, that will scan all the block devices of the computer to find a linux system. The first linux system found on the disks 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 with your kernel for instance. You can have <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> about that option.
153     </li><li><b>initscript=service:action</b>: This options allows you to automatically start/stop a service at boot time. For instance if you need the samba service to be started, you can boot with the following option: <code>initscript=samba:start</code>. This does the same thing as <code>/etc/init.d/samba start</code>. You can use this option several times with different services. All the action that are supported by an initscript can be used. This option is available with SystemRescueCd-1.0.2 and newer.
154     </li><li><b>backstore=xxx</b>: SystemRescueCd-1.1.x 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>. Basically, a backing-store is a loopback filesystem which saves all the changes you can make in SystemRescueCd when you use it. In other words it allows you to save all the files which changes in SystemRescueCd while you use it, so that you keep these changes the next time you boot it. By default, sysresccd automatically scan all your removable devices (eg: usb sticks) at boot time and uses the first backing-store it finds if there is one. A backing-store is not mandatory and it the scan fails it will just store the files which change in memory. To disable the disks scan at boot time you can specify <code>backstore=off</code> on the boot command line. If you want to save your backing-store file on an harddisk, you will have to boot with <code>backstore=alldev</code> so that it scans all devices not just removable devices. The default place for backing-stores file is any file named <code>sysrcd.bs</code> located at the root of a disk which is often an USB key. You can change the path by using an option such as <code>backstore=/sysrcd/mybackstore.bs</code> and then sysresccd will try to find a file named <code>mybackstore.bs</code> located in <code>/sysrcd</code> in any block-device (partition, USB-stick, ...). You can find more information about on the page about <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>.

156    
157     <p><b><BR>Hardware, drivers and troubleshooting options</b></p>
158    
159     <ul><li><b>nonet</b>: this will disable the network auto detection at startup
160     </li><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.
161     </li><li><b>doxdetect</b>: Since version 0.3.5 the auto-configuration is done in X.Org itself, and then mkxf86config is disabled by default. This option forces the system to run the mkxf86config startup script 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.
162     </li><li><b>nodetect</b>: prevents the generic hardware auto-detection. Use this option if you have problems with the hardware auto-detection.
163     </li><li><b>doload=xxx</b>: forces to load one/several modules at startup (example: <code>doload=3c59x</code>)
164     </li><li><b>noload=xxx</b>: prevents the system to load one/several modules at startup (example: <code>noload=3c59x</code>). Use this option if you have a problem when the system loads a particular module at boot time.
165     </li><li><b>dostartx</b>: This option will force the system to load the X.Org graphical environment at boot time. You won't have to type <code>startx</code> by hand to get it.
166     </li><li><b>forcevesa</b>: Forces X.Org to work with 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.
167     </li><li><b>forcevesa=xxx</b>: The <code>startx</code> command will load the <code>Xvesa</code> server instead of <code>Xorg</code>, and Xvesa will use the screen resolution given as parameter (eg: <code>1024x768</code>, <code>1280x1024x32</code>). The <code>forcevesa</code> option can take a parameter from SystemRescueCd-1.0.0 and more recent.
168     </li><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>)
169     </li><li><b>acpi-off</b> / <b>noapic</b> / <b>irqpool</b>: use these options if you have any problem when the kernel boots: if it hangs on a driver or if it crashes, ...
170     </li><li><b>dodebug</b>: Enables verbose messages in the linuxrc script.
171     </li><li><b>lowmem</b>: Prevents non critical things to be loaded into memory (like the sshd and nfsd services)
172     </li><li><b>skipmount=/dev/xxx</b>: The system mounts all the storage devices at boot time to find the sysrcd.dat file. You may not want it to mount a device, for instance if your hard disk is broken because it would crash the system. You can just boot with <code>skipmount=/dev/sda1 skipmount=/dev/sda2</code> if you want SystemRescueCd to ignore these two partitions. This boot option requires SystemRescueCd-1.0.1 or more recent.
173     </li><li><b>nodmraid</b>: Disable dmraid, which is the program that drives RAID disks based on cheap RAID controller built-in motherboards.
174     </li><li><b>nomdadm</b>: Disable mdadm, which is the program that drives software RAID.
175     </li></ul>
176    
177     <p><b><BR>Network auto-configuration and remote access</b></p>
178    
179     <ul><li><b>dodhcp</b>: Use <code>dodhcp</code> if you have a DHCP server on your network and you want the system to get a dynamic IP address at boot time.
180     </li><li><b>ethx=ipaddr/cidr</b>: Sets the static IP address of all the ethernet interfaces found 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 also write something like <code>ethx=10.0.0.1/24</code> (using the cidr notation) if you don't use the default netmask.
181     </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. Of course, you can use <a href="http://www.sysresccd.org/news/2008/04/13/new-boot-options-for-advanced-ethernet-ip-configuration/" class="external text" title="http://www.sysresccd.org/news/2008/04/13/new-boot-options-for-advanced-ethernet-ip-configuration/" rel="nofollow">the eth0=ipaddr/cidr option</a> it for all the ethernet interfaces, not just eth0. For instance if you want to configure the network on a server that has two interfaces, you can write something like this: <code>eth0=192.168.10.1/24 eth1=192.168.20.1</code>. This option requires SystemRescueCd-1.0.2 or newer.
182     </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.
183     </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>.
184     </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.
185     </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.
186     </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).

222    
223     <!-- Start of copy/paste 3 -->
224     <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:
225     <ol>
226     <li>Boot parameters from live-initramfs. You can refer to this <a href="#live-initramfs">manual of live-initramfs</a>.
227     <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.
228     <ul>
229     <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>
230     e.g. ocs_live_run="ocs-live-general"
231     <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>
232     e.g. ocs_live_extra_param="-b -c restoredisk sarge-r5 hda"
233     <li>ocs_live_keymap is for keymap used in Clonezilla live. Man install-keymap for more details.<br>
234     e.g. ocs_live_keymap="NONE" (won't change the default layout)<br>
235     ocs_live_keymap="/usr/share/keymaps/i386/azerty/fr-latin9.kmap.gz" (French keyboard)
236     <li>batch mode or not (yes/no), if no, will run interactively.<br>
237     e.g. ocs_live_batch="no"
238     <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/)
239     e.g. ocs_lang="en_US.UTF-8"
240     <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.
241     <li>ocs_daemonon, ocs_daemonoff, ocs_numlk, ocs_capslk.<br>
242     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.
243     <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.
244     <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.
245     <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.
246     </ul>
247     </ol>
248     <hr>
249    
250     With the above options, we have the following examples:
251     <ol>
252     <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>
253     ----------------------------------------<br>
254     label Clonezilla Live<br>
255     MENU LABEL Clonezilla Live<br>
256     MENU DEFAULT<br>
257     kernel vmlinuz1<br>
258     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>
259     ----------------------------------------<br>
260    
261     The usercrypted password is created by:<br>
262     echo YOUR_PASSWORD | mkpasswd -s<br>
263     ("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>
264     //NOTE// If you do not assign salt to mkpasswd, the encrypted password will not be the same every time you create it.<br>
265     For more about usercrypted discussion, please check the <a href="http://lists.debian.org/debian-live/2008/10/msg00020.html" target=_blank>here</a>.
266     <br><br>
267     <li>How to put your own binary driver in Clonezilla live without modifying /live/filesystem.squashfs:
268     <ul>
269     <li>Boot clonezilla live
270     <li>Become root by running "sudo su -"
271     <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>
272     cp -r /live/image/lsi /home/partimag
273     <li>cd /home/partimag
274     <li>/opt/drbl/sbin/ocs-live-dev -c -s -i lsi -u lsi -x "ocs_prerun=/live/image/lsi/prep-lsi.sh"
275     <li>/opt/drbl/sbin/ocs-iso -s -i lsi -u lsi -x "ocs_prerun=/live/image/lsi/prep-lsi.sh"
276     <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:
277     <pre>
278     ------------------------
279     #!/bin/bash
280     cp -f /live/image/lsi/megasr.ko /lib/modules/`uname -r`/kernel/drivers/block/
281     chown root.root /lib/modules/`uname -r`/kernel/drivers/block/megasr.ko
282     depmod -a modprobe megasr
283     sleep 1
284     ------------------------
285     </pre>
286     </ul>
287    
288     <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>
289     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>
290     Therefor your pxelinux.cfg/default file is like:

342     =================
343    
344     Name
345     ----
346     live-initramfs - Debian Live initramfs hook
347    
348     Synopsis
349     --------
350     BOOT=live
351    
352     as kernel parameter at boot prompt.
353    
354     Description
355     -----------
356    
357     live-initramfs is a hook for the initramfs-tools, used to generate a initramfs
358     capable to boot live systems, such as those created by *live-helper*(7).
359     This includes the Debian Live isos, netboot tarballs, and usb stick images.
360    
361     At boot time it will look for a (read-only) media containing a "/live"
362     directory where a root filesystems (often a compressed filesystem image like
363     squashfs) is stored. If found, it will create a writable environment, using
364     aufs, for Debian like systems to boot from.
365    
366     You probably do not want to install this package onto a non-live system,
367     although it will do no harm.
368    
369     live-initramfs is a fork of link:http://packages.ubuntu.com/casper/[casper].
370     casper was originally written by Tollef Fog Heen &lt;tfheen@canonical.com&gt;
371     and Matt Zimmerman &lt;mdz@canonical.com&gt;.
372    
373     Boot options
374     ------------
375    
376     Here is the complete list of recognized boot parameters by live-initramfs.
377    
378     access=*ACCESS*::
379    
380     Set the accessibility level for physically or visually impared users. ACCESS
381     must be one of v1, v2, v3, m1, or m2. v1=lesser visual impairment, v2=moderate
382     visual impairment, v3=blindness, m1=minor motor difficulties, m2=moderate motor
383     difficulties.
384    
385     console=*TTY,SPEED*::
386    
387     Set the default console to be used with the "live-getty" option. Example:
388     "console=ttyS0,115200"
389    
390     debug::
391    
392     Makes initramfs boot process more verbose.
393    
394     fetch=*URL*::
395    
396     Another form of netboot by downloading a squashfs image from a given url,
397     copying to ram and booting it.
398    
399     hostname=*HOSTNAME*, username=*USER*, userfullname=*USERFULLNAME*::
400    
401     Those parameters lets you override values read from the config file.
402    
403     ignore_uuid
404    
405     Do not check that any UUID embedded in the initramfs matches the discovered
406     medium. live-initramfs may be told to generate a UUID by setting
407     LIVE_GENERATE_UUID=1 when building the initramfs.
408    
409     integrity-check::
410    
411     If specified, an MD5 sum is calculated on the live media during boot and
412     compared to the value found in md5sum.txt found in the root directory of the
413     live media.
414    
415     ip=**[CLIENT_IP]:[SERVER_IP]:[GATEWAY_IP]:[NETMASK]:[HOSTNAME]:[DEVICE]:[AUTOCONF]
416     [,[CLIENT_IP]:[SERVER_IP]:[GATEWAY_IP]:[NETMASK]:[HOSTNAME]:[DEVICE]:[AUTOCONF]]***::
417    
418     Let you specify the name(s) and the options of the interface(s) that should be
419     configured at boot time. Do not specify this if you want to use dhcp (default).
420     It will be changed in a future release to mimick official kernel boot param
421     specification (e.g. ip=10.0.0.1::10.0.0.254:255.255.255.0::eth0,:::::eth1:dhcp).
422    
423     ip[=**frommedia**]::
424    
425     If this variable is set, dhcp and static configuration are just skipped and the
426     system will use the (must be) media-preconfigured /etc/network/interfaces
427     instead.
428    
429     {keyb|kbd-chooser/method}=**KEYBOARD**, {klayout|console-setup/layoutcode}=**LAYOUT**,
430     {kvariant|console-setup/variantcode}=**VARIANT**,
431     {kmodel|console-setup/modelcode}=**CODE**, koptions=**OPTIONS**::
432    
433     Configure the running keyboard as specified, if this one misses live-initramfs
434     behaves as if "keyb=us" was specified. It will be interfered from "locale=" if
435     locale is only 2 lowecase letters as a special case. You could also specify
436     console layout, variant, code, and options (no defaults).
437    
438     live-getty::
439    
440     This changes the auto-login on virtual terminals to use the (experimental)
441     live-getty code. With this option set the standard kernel argument "console=" is
442     parsed and if a serial console is specified then live-getty is used to autologin
443     on the serial console.
444    
445     {live-media|bootfrom}=**DEVICE**::
446    
447     If you specify one of this two equivalent forms, live-initramfs will first try
448     to find this device for the "/live" directory where the read-only root
449     filesystem should reside. If it did not find something usable, the normal scan
450     for block devices is performed.
451    
452     {live-media-encryption|encryption}=**TYPE**::
453    
454     live-initramfs will mount the encrypted rootfs TYPE, asking the passphrase,
455     useful to build paranoid live systems :-). TYPE supported so far are "aes" for
456     loop-aes encryption type.
457    
458     live-media-offset=**BYTES**::
459    
460     This way you could tell live-initramfs that your image starts at offset BYTES in
461     the above specified or autodiscovered device, this could be useful to hide the
462     Debian Live iso or image inside another iso or image, to create "clean" images.
463    
464     live-media-path=**PATH**::
465    
466     Sets the path to the live filesystem on the medium. By default, it is set to
467     '/live' and you should not change that unless you have customized your media
468     accordingly.
469    
470     live-media-timeout=**SECONDS**::
471    
472     Set the timeout in seconds for the device specified by "live-media=" to become
473     ready before giving up.
474    
475     {locale|debian-installer/locale}=**LOCALE**::
476    
477     Configure the running locale as specified, if not present the live-media rootfs
478     configured locale will be used and if also this one misses live-initramfs behave
479     as "locale=en_US.UTF-8" was specified. If only 2 lowercase letter are specified
480     (like "it"), the "maybe wanted" locale is generated (like en:EN.UTF-8), in this
481     case if also "keyb=" is unspecified is set with those 2 lowercase letters
482     (keyb=us). Beside that facility, only UTF8 locales are supported by
483     live-initramfs.
484    
485     module=**NAME**::
486    
487     Instead of using the default optional file "filesystem.module" (see below)
488     another file could be specified without the extension ".module"; it should be
489     placed on "/live" directory of the live medium.
490    
491     netboot[=**nfs**|**cifs**]::
492    
493     This tells live-initramfs to perform a network mount. The parameter "nfsroot="
494     (with optional "nfsopts="), should specify where is the location of the root
495     filesystem. With no args, will try cifs first, and if it fails nfs.
496    
497     nfsopts=::
498    
499     This lets you specify custom nfs options.
500    
501     noautologin::
502    
503     This parameter disables the automatic terminal login only, not touching gdk/kdm.
504    
505     noxautologin::
506    
507     This parameter disables the automatic login of gdm/kdm only, not touching
508     terminals.
509    
510     nofastboot::
511    
512     This parameter disables the default disabling of filesystem checks in
513     /etc/fstab. If you have static filesystems on your harddisk and you want them to
514     be checked at boot time, use this parameter, otherwise they are skipped.
515    
516     nopersistent::
517    
518     disables the "persistent" feature, useful if the bootloader (like syslinux) has
519     been installed with persistent enabled.
520    
521     noprompt
522    
523     Do not prompt to eject the CD on reboot.
524    
525     nosudo::
526    
527     This parameter disables the automatic configuration of sudo.
528    
529     swapon::
530    
531     This parameter enables usage of local swap partitions.
532    
533     nouser::
534    
535     This parameter disables the creation of the default user completely.
536    
537     noxautoconfig::
538    
539     This parameter disables Xorg auto-reconfiguration at boot time. This is valuable
540     if you either do the detection on your own, or, if you want to ship a custom,
541     premade xorg.conf in your live system.
542    
543     persistent[=nofiles]::
544    
545     live-initramfs will look for persistent and snapshot partitions or files labeled
546     "live-rw", "home-rw", and files called "live-sn*", "home-sn*" and will try to,
547     in order: mount as /cow the first, mount the second in /home, and just copy the
548     contents of the latter in appropriate locations (snapshots). Snapshots will be
549     tried to be updated on reboot/shutdown. Look at live-snapshot(1) for more
550     informations. If "nofiles" is specified, only filesystems with matching labels
551     will be searched; no filesystems will be traversed looking for archives or image
552     files. This results in shorter boot times.
553    
554     {preseed/file|file}=**FILE**::
555    
556     A path to a file present on the rootfs could be used to preseed debconf
557     database.
558    
559     package/question=**VALUE**::
560    
561     All debian installed packages could be preseeded from command-line that way,
562     beware of blanks spaces, they will interfere with parsing, use a preseed file in
563     this case.
564    
565     quickreboot::
566    
567     This option causes live-initramfs to reboot without attempting to eject the
568     media and without asking the user to remove the boot media.
569    
570     showmounts::
571    
572     This parameter will make live-initramfs to show on "/" the ro filesystems
573     (mostly compressed) on "/live". This is not enabled by default because could
574     lead to problems by applications like "mono" which store binary paths on
575     installation.
576    
577     textonly
578    
579     Start up to text-mode shell prompts, disabling the graphical user interface.
580    
581     timezone=**TIMEZONE**::
582    
583     By default, timezone is set to UTC. Using the timezone parameter, you can set it
584     to your local zone, e.g. Europe/Zurich.
585    
586     todisk=**DEVICE**::
587    
588     Adding this parameter, live-initramfs will try to copy the entire read-only
589     media to the specified device before mounting the root filesystem. It probably
590     needs a lot of free space. Subsequent boots should then skip this step and just
591     specify the "live-media=DEVICE" boot parameter with the same DEVICE used this
592     time.
593    
594     toram::
595    
596     Adding this parameter, live-initramfs will try to copy the whole read-only media
597     to the computer's RAM before mounting the root filesystem. This could need a lot
598     of ram, according to the space used by the read-only media.
599    
600     union=**aufs**|**unionfs**::
601    
602     By default, live-initramfs uses aufs. With this parameter, you can switch to
603     unionfs.
604    
605     utc=**yes**|**no**::
606    
607     By default, Debian systems do assume that the hardware clock is set to UTC. You
608     can change or explicitly set it with this parameter.
609    
610     xdebconf::
611    
612     Uses xdebconfigurator, if present on the rootfs, to configure X instead of the
613     standard procedure (experimental).
614    
615     xvideomode=**RESOLUTION**::
616    
617     Doesn't do xorg autodetection, but enforces a given resolution.
618    
619     Files
620     -----
621    
622     /etc/live.conf
623    
624     Some variables can be configured via this config file (inside the live system).
625    
626     /live/filesystem.module
627    
628     This optional file (inside the live media) contains a list of white-space or
629     carriage-return-separated file names corresponding to disk images in the "/live"
630     directory. If this file exists, only images listed here will be merged into the
631     root aufs, and they will be loaded in the order listed here. The first entry
632     in this file will be the "lowest" point in the aufs, and the last file in
633     this list will be on the "top" of the aufs, directly below /cow. Without
634     this file, any images in the "/live" directory are loaded in alphanumeric order.
635    
636     /etc/live-persistence.binds
637    
638     This optional file (which resides in the rootfs system, not in the live media)
639     is used as a list of directories which not need be persistent: ie. their
640     content does not need to survive reboots when using the persistence features.
641    
642     This saves expensive writes and speeds up operations on volatile data such as
643     web caches and temporary files (like e.g. /tmp and .mozilla) which are
644     regenerated each time. This is achieved by bind mounting each listed directory
645     with a tmpfs on the original path.
