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.

153 sng 75 <p>Press &lt;TAB&gt; to add additional options (in SystemRescueCd-1.5 and more recent)
154 sng 40 </p>
155     <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.
156 sng 75 </li><li><b>setkmap=kk</b>: which defines the keymap to load where <code>kk</code> (example: <code>setkmap=de</code> for German keyboards). This way you won't be prompted for the keyboard configuration during the boot.
157 sng 56 </li><li><b>root=/dev/xdnp</b>: the <a target="_blank" 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 target="_blank" 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>.
158 sng 40 </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.
159 sng 56 </li><li><b>backstore=xxx</b>: SystemRescueCd comes with support for the <a target="_blank" 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 target="_blank" 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>.
160     </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 target="_blank" 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.

168     </li></ul>
169     <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.
170     </li></ul>
171     <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.
172     </li><li><b>nodetect</b>: prevents generic hardware auto-detection. Use this option if you have problems with the hardware auto-detection.
173     </li></ul>
174     <ul><li><b>dostartx</b>: load the X.Org graphical environment.
175     </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.
176     </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>).

You can use this option if you want to configure the network using these commands. This option is not necessary when SystemRescueCd is booting from the network since the service is automatically stopped in that case. This option requires SystemRescueCd-1.5.5 or more recent.

191     </li><li><b>nodhcp</b>: never run the dhcp client in the initramfs boot script. May be useful if you use PXE boot on a computer with several ethernet interfaces. Support for this option is available in SystemRescueCd-1.5.5-beta2 and more recent
192 sng 40 </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=</code> on a machine with two ethernet adapters, both <code>eth0</code> and <code>eth1</code> will be configured with <code></code>. You can use the format <code>ethx=</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= eth1=</code>.

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.

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.

251 sng 56 <div class="otherpage">Clonezilla live is based on <a target="_blank" href="http://wiki.debian.org/DebianLive/" >Debian live</a> with clonezilla installed. Therefore there are 2 kinds of boot parameters:
252 sng 28 <ol>
253 sng 41 <li>Boot parameters from live-initramfs. You can refer to this <a href="#live-initramfs">manual of live-initramfs</a>.
254 sng 28 <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 sng 40 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 sng 28 <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 sng 40 <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, netmask, gateway, DNS server, you can assign the following in the boot parameter:<br>
280     ip=eth0,,,,<br>
281     If more than one network card, you can use ":" to separate them, e.g.:<br>
282     ip=eth0,,,,,,,,,<br>
283 sng 28 <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>
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>

296     append initrd=initrd1.img boot=live union=aufs noswap noprompt vga=788 fetch=tftp:// usercrypted=bkuQxLqLRuDW6 ocs_numlk="on" ocs_daemonon="ssh"<br>
297     ----------------------------------------<br>
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>
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, (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>

385     Name
386     ----
387     live-initramfs - Debian Live initramfs hook
389     Synopsis
390     --------
391     BOOT=live
393     as kernel parameter at boot prompt.
395     Description
396     -----------
398     live-initramfs is a hook for the initramfs-tools, used to generate a initramfs
399     capable to boot live systems, such as those created by *live-helper*(7).
400     This includes the Debian Live isos, netboot tarballs, and usb stick images.
402     At boot time it will look for a (read-only) media containing a "/live"
403     directory where a root filesystems (often a compressed filesystem image like
404     squashfs) is stored. If found, it will create a writable environment, using
405     aufs, for Debian like systems to boot from.
407     You probably do not want to install this package onto a non-live system,
408     although it will do no harm.
410 sng 56 live-initramfs is a fork of <a href="http://packages.ubuntu.com/casper/" target="_blank">casper</a>.
411     casper was originally written by Tollef Fog Heen &amp;lt;tfheen@canonical.com&amp;gt;
412     and Matt Zimmerman &amp;lt;mdz@canonical.com&amp;gt;.
413 sng 28
414     Boot options
415     ------------
417     Here is the complete list of recognized boot parameters by live-initramfs.
419 sng 56 access=*ACCESS*::
420 sng 28
421     Set the accessibility level for physically or visually impared users. ACCESS
422     must be one of v1, v2, v3, m1, or m2. v1=lesser visual impairment, v2=moderate
423     visual impairment, v3=blindness, m1=minor motor difficulties, m2=moderate motor
424     difficulties.
426 sng 56 console=*TTY,SPEED*::
427 sng 28
428     Set the default console to be used with the "live-getty" option. Example:
429     "console=ttyS0,115200"
431 sng 56 debug::
432 sng 28
433     Makes initramfs boot process more verbose.
435 sng 56 fetch=*URL*::
436 sng 28
437     Another form of netboot by downloading a squashfs image from a given url,
438     copying to ram and booting it.
440 sng 56 hostname=*HOSTNAME*, username=*USER*, userfullname=*USERFULLNAME*::
441 sng 28
442     Those parameters lets you override values read from the config file.
444 sng 56 ignore_uuid
445 sng 28
446     Do not check that any UUID embedded in the initramfs matches the discovered
447     medium. live-initramfs may be told to generate a UUID by setting
448     LIVE_GENERATE_UUID=1 when building the initramfs.
450 sng 56 integrity-check::
451 sng 28
452     If specified, an MD5 sum is calculated on the live media during boot and
453     compared to the value found in md5sum.txt found in the root directory of the
454     live media.
458     [DEVICE]:[AUTOCONF]]***::
459 sng 28
460     Let you specify the name(s) and the options of the interface(s) that should be
461     configured at boot time. Do not specify this if you want to use dhcp (default).
462     It will be changed in a future release to mimick official kernel boot param
463     specification (e.g. ip=,:::::eth1:dhcp).
465 sng 56 ip[=**frommedia**]::
466 sng 28
467     If this variable is set, dhcp and static configuration are just skipped and the
468     system will use the (must be) media-preconfigured /etc/network/interfaces
469     instead.
471 sng 56 {keyb|kbd-chooser/method}=**KEYBOARD**, {klayout|console-setup/layoutcode}=**LAYOUT**,
472     {kvariant|console-setup/variantcode}=**VARIANT**, {kmodel|console-setup/modelcode}=
473     **CODE**, koptions=**OPTIONS**::
474 sng 28
475     Configure the running keyboard as specified, if this one misses live-initramfs
476     behaves as if "keyb=us" was specified. It will be interfered from "locale=" if
477     locale is only 2 lowecase letters as a special case. You could also specify
478     console layout, variant, code, and options (no defaults).
480 sng 56 live-getty::
481 sng 28
482     This changes the auto-login on virtual terminals to use the (experimental)
483     live-getty code. With this option set the standard kernel argument "console=" is
484     parsed and if a serial console is specified then live-getty is used to autologin
485     on the serial console.
487 sng 56 {live-media|bootfrom}=**DEVICE**::
488 sng 28
489     If you specify one of this two equivalent forms, live-initramfs will first try
490     to find this device for the "/live" directory where the read-only root
491     filesystem should reside. If it did not find something usable, the normal scan
492     for block devices is performed.
494 sng 56 {live-media-encryption|encryption}=**TYPE**::
495 sng 28
496     live-initramfs will mount the encrypted rootfs TYPE, asking the passphrase,
497     useful to build paranoid live systems :-). TYPE supported so far are "aes" for
498     loop-aes encryption type.
500 sng 56 live-media-offset=**BYTES**::
501 sng 28
502     This way you could tell live-initramfs that your image starts at offset BYTES in
503     the above specified or autodiscovered device, this could be useful to hide the
504     Debian Live iso or image inside another iso or image, to create "clean" images.
506 sng 56 live-media-path=**PATH**::
507 sng 28
508     Sets the path to the live filesystem on the medium. By default, it is set to
509     '/live' and you should not change that unless you have customized your media
510     accordingly.
512 sng 56 live-media-timeout=**SECONDS**::
513 sng 28
514     Set the timeout in seconds for the device specified by "live-media=" to become
515     ready before giving up.
517 sng 56 {locale|debian-installer/locale}=**LOCALE**::
518 sng 28
519     Configure the running locale as specified, if not present the live-media rootfs
520     configured locale will be used and if also this one misses live-initramfs behave
521     as "locale=en_US.UTF-8" was specified. If only 2 lowercase letter are specified
522     (like "it"), the "maybe wanted" locale is generated (like en:EN.UTF-8), in this
523     case if also "keyb=" is unspecified is set with those 2 lowercase letters
524     (keyb=us). Beside that facility, only UTF8 locales are supported by
525     live-initramfs.
527 sng 56 module=**NAME**::
528 sng 28
529     Instead of using the default optional file "filesystem.module" (see below)
530     another file could be specified without the extension ".module"; it should be
531     placed on "/live" directory of the live medium.
533 sng 56 netboot[=**nfs**|**cifs**]::
534 sng 28
535     This tells live-initramfs to perform a network mount. The parameter "nfsroot="
536     (with optional "nfsopts="), should specify where is the location of the root
537     filesystem. With no args, will try cifs first, and if it fails nfs.
539 sng 56 nfsopts=::
540 sng 28
541     This lets you specify custom nfs options.
543 sng 56 noautologin::
544 sng 28
545     This parameter disables the automatic terminal login only, not touching gdk/kdm.
547 sng 56 noxautologin::
548 sng 28
549     This parameter disables the automatic login of gdm/kdm only, not touching
550     terminals.
552 sng 56 nofastboot::
553 sng 28
554     This parameter disables the default disabling of filesystem checks in
555     /etc/fstab. If you have static filesystems on your harddisk and you want them to
556     be checked at boot time, use this parameter, otherwise they are skipped.
558 sng 56 nopersistent::
559 sng 28
560     disables the "persistent" feature, useful if the bootloader (like syslinux) has
561     been installed with persistent enabled.
563 sng 56 noprompt
564 sng 28
565     Do not prompt to eject the CD on reboot.
567 sng 56 nosudo::
568 sng 28
569     This parameter disables the automatic configuration of sudo.
571 sng 56 swapon::
572 sng 28
573     This parameter enables usage of local swap partitions.
575 sng 56 nouser::
576 sng 28
577     This parameter disables the creation of the default user completely.
579 sng 56 noxautoconfig::
580 sng 28
581     This parameter disables Xorg auto-reconfiguration at boot time. This is valuable
582     if you either do the detection on your own, or, if you want to ship a custom,
583     premade xorg.conf in your live system.
585 sng 56 persistent[=nofiles]::
586 sng 28
587     live-initramfs will look for persistent and snapshot partitions or files labeled
588     "live-rw", "home-rw", and files called "live-sn*", "home-sn*" and will try to,
589     in order: mount as /cow the first, mount the second in /home, and just copy the
590     contents of the latter in appropriate locations (snapshots). Snapshots will be
591     tried to be updated on reboot/shutdown. Look at live-snapshot(1) for more
592     informations. If "nofiles" is specified, only filesystems with matching labels
593     will be searched; no filesystems will be traversed looking for archives or image
594     files. This results in shorter boot times.
596 sng 56 {preseed/file|file}=**FILE**::
597 sng 28
598     A path to a file present on the rootfs could be used to preseed debconf
599     database.
601 sng 56 package/question=**VALUE**::
602 sng 28
603     All debian installed packages could be preseeded from command-line that way,
604     beware of blanks spaces, they will interfere with parsing, use a preseed file in
605     this case.
607 sng 56 quickreboot::
608 sng 28
609     This option causes live-initramfs to reboot without attempting to eject the
610     media and without asking the user to remove the boot media.
612 sng 56 showmounts::
613 sng 28
614     This parameter will make live-initramfs to show on "/" the ro filesystems
615     (mostly compressed) on "/live". This is not enabled by default because could
616     lead to problems by applications like "mono" which store binary paths on
617     installation.
619 sng 56 textonly
620 sng 28
621     Start up to text-mode shell prompts, disabling the graphical user interface.
623 sng 56 timezone=**TIMEZONE**::
624 sng 28
625     By default, timezone is set to UTC. Using the timezone parameter, you can set it
626     to your local zone, e.g. Europe/Zurich.
628 sng 56 todisk=**DEVICE**::
629 sng 28
630     Adding this parameter, live-initramfs will try to copy the entire read-only
631     media to the specified device before mounting the root filesystem. It probably
632     needs a lot of free space. Subsequent boots should then skip this step and just
633     specify the "live-media=DEVICE" boot parameter with the same DEVICE used this
634     time.
636 sng 56 toram::
637 sng 28
638     Adding this parameter, live-initramfs will try to copy the whole read-only media
639     to the computer's RAM before mounting the root filesystem. This could need a lot
640     of ram, according to the space used by the read-only media.
642 sng 56 union=**aufs**|**unionfs**::
643 sng 28
644     By default, live-initramfs uses aufs. With this parameter, you can switch to
645     unionfs.
647 sng 56 utc=**yes**|**no**::
648 sng 28
649     By default, Debian systems do assume that the hardware clock is set to UTC. You
650     can change or explicitly set it with this parameter.
652 sng 56 xdebconf::
653 sng 28
654     Uses xdebconfigurator, if present on the rootfs, to configure X instead of the
655     standard procedure (experimental).
657 sng 56 xvideomode=**RESOLUTION**::
658 sng 28
659     Doesn't do xorg autodetection, but enforces a given resolution.
661     Files
662     -----
664 sng 56 /etc/live.conf
665 sng 28
666     Some variables can be configured via this config file (inside the live system).
668 sng 56 /live/filesystem.module
669 sng 28
670     This optional file (inside the live media) contains a list of white-space or
671     carriage-return-separated file names corresponding to disk images in the "/live"
672     directory. If this file exists, only images listed here will be merged into the
673     root aufs, and they will be loaded in the order listed here. The first entry
674     in this file will be the "lowest" point in the aufs, and the last file in
675     this list will be on the "top" of the aufs, directly below /cow. Without
676     this file, any images in the "/live" directory are loaded in alphanumeric order.
678 sng 56 /etc/live-persistence.binds
679 sng 28
680     This optional file (which resides in the rootfs system, not in the live media)
681     is used as a list of directories which not need be persistent: ie. their
682     content does not need to survive reboots when using the persistence features.
684     This saves expensive writes and speeds up operations on volatile data such as
685     web caches and temporary files (like e.g. /tmp and .mozilla) which are
686     regenerated each time. This is achieved by bind mounting each listed directory
687     with a tmpfs on the original path.
