122     <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.
123     <br><br>
124     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>.
125     <br><br>
126     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.
127     <br><br>
128     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.

166 sng 75 <p>Press &lt;TAB&gt; to add additional options (in SystemRescueCd-1.5 and more recent)
167 sng 40 </p>
168 sng 144 <ul><li><b>docache</b>: causes the CD-ROM to 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 from being copied.
169 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.
170 sng 144 </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 for a linux system. The first linux system found will be started. So <code>root=auto</code> lets 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>.
171     </li><li><b>initscript=service:action</b>: This option allows one to 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 a multiple of times for different services. All the actions that are supported by an initscript can be used.
172     </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. 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 if the scan fails, it will store the files which have changed 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 a harddisk, boot with <code>backstore=alldev</code> to scan all devices (not just removable devices). The default location for a backing-stores file is any file named <code>sysrcd.bs</code> located at the root of a disk which is often a 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>.
173     </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 on 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.

184     <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.
185     </li><li><b>nodetect</b>: prevents generic hardware auto-detection. Use this option if you have problems with the hardware auto-detection.

203 sng 75 <ul><li><b>nonm</b>: to disable the Network-Manager service that conflicts with the standard network command line tools such as <code>ifconfig</code> and <code>ip</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.
204 sng 163 </li><li><b>dodhcp</b>: to request a DHCP server provide network attributes including an IP address, gateway... If there are multiple interfaces on the computer it will run the dhcp client on all of them by default, when no argument is specified with this option. Thanks to <a target="_blank" href="http://www.sysresccd.org/forums/viewtopic.php?f=5&amp;t=3454" class="external text" title="http://www.sysresccd.org/forums/viewtopic.php?f=5&amp;t=3454" rel="nofollow">emiliano</a> SystemRescueCd-1.7.0-beta009 and more recent allows you to optionally specify which interfaces should be configured with dhcp. This way you can combine static and dynamic addresses in the automatic Ethernet configuration. For example you can now use options like that: <pre>dodhcp=eth0,eth2 eth1=</pre> to use dhcp for eth0 and eth2 and a static address on eth1.
205 sng 144 </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 and more recent
206 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.
207 sng 144 </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, for example: <code>eth0= eth1=</code>.
208 sng 28 </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=</code> means that you want to use <code></code> as the DNS server.
209     </li><li><b>gateway=ipaddr</b>: Sets the static IP address of the default route on your network. For instance <code>gateway=</code> means that the computer can connect to a computer outside of the local network via <code></code>.
210     </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.
211 sng 144 </li><li><b>rootpass=123456</b>: Sets the root password of the system running on the livecd to <code>123456</code>. That way you can connect from the network and ssh on the livecd and give <code>123456</code> password as the root password.
212     </li><li><b>vncserver=x:123456</b>: The <a target="_blank" 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 6 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. SystemRescueCd-1.5.7 and more recent accept a password longer than 8 chars (between 5 and 12 chars)

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). You can also use the magic keyword <a target="_blank" href="http://www.sysresccd.org/forums/viewtopic.php?f=7&amp;t=2538&amp;start=0" class="external text" title="http://www.sysresccd.org/forums/viewtopic.php?f=7&amp;t=2538&amp;start=0" rel="nofollow">BOOTIF</a> with SystemRescueCd-1.5.4 and more recent when you boot from pxelinux. The pxeboot loader will set BOOTIF to the name of the interface used to boot. You can then use something like <code>nameif=eth0!BOOTIF</code> if you want the boot interface to be called <code>eth0</code> on a computer with several Ethernet interfaces.

216 sng 40 <p>SystemRescueCd provides several options for booting from the network using PXE.
217 sng 56 These options can be combined with other network boot options such as <code>ethx</code> (cf previous section).

221     </p>
222     <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.
223     </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.
224 sng 144 </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 allows computers with smaller memory to boot SystemRescueCd from the network. After the boot process, continued network connection is required or you will loose access to the root file system.
225     </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 memory to boot SystemRescueCd from the network. After the boot process, the network connection continues to be required to access the root file system.

265 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:
266 sng 28 <ol>
267 sng 41 <li>Boot parameters from live-initramfs. You can refer to this <a href="#live-initramfs">manual of live-initramfs</a>.
268 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.
269     <ul>
270     <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>
271 sng 40 e.g. ocs_live_run="ocs-live-general"<br>
272     <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>
273 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>
274 sng 144 e.g. ocs_live_extra_param="--batch -c restoredisk sarge-r5 hda"
275 sng 28 <li>ocs_live_keymap is for keymap used in Clonezilla live. Man install-keymap for more details.<br>
276     e.g. ocs_live_keymap="NONE" (won't change the default layout)<br>
277     ocs_live_keymap="/usr/share/keymaps/i386/azerty/fr-latin9.kmap.gz" (French keyboard)
278     <li>batch mode or not (yes/no), if no, will run interactively.<br>
279     e.g. ocs_live_batch="no"
280     <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/)
281     e.g. ocs_lang="en_US.UTF-8"
282     <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.
283     <li>ocs_daemonon, ocs_daemonoff, ocs_numlk, ocs_capslk.<br>
284     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.
285 sng 163 <li>ocs_prerun, ocs_prerun1, ocs_prerun2... is for you to run a command 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.
286     <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. If you want to use ttyS0, for example, add live-getty and console=ttyS0,38400n81 in the boot parameter.<br>
287 sng 40 <font color=red>//NOTE//</font><br>
288     <ul>
289 sng 144 <li>If "live-getty console=ttyS0,38400n81" are assigned in the boot parameters, ocs_live_run_tty will honor ttyS0, even other value is assigned to ocs_live_run_tty in boot parameter.
290 sng 40 <li>It's recommended to assign ocs_lang and ocs_live_keymap in the boot parameters too.
291     </ul>
292     <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>
293 sng 163 ip=eth0:<br>
294     If more than one network card, you can use "," to separate them, e.g.:<br>
295     ip=eth0:,eth1:<br>
296 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.
297     </ul>
298     </ol>
299     <hr>
301     With the above options, we have the following examples:
302     <ol>
303     <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>

310     ----------------------------------------<br>
312     The usercrypted password is created by:<br>
313     echo YOUR_PASSWORD | mkpasswd -s<br>
314     ("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>
315     //NOTE// If you do not assign salt to mkpasswd, the encrypted password will not be the same every time you create it.<br>

318     <li>How to put your own binary driver in Clonezilla live without modifying /live/filesystem.squashfs:
319     <ul>
320     <li>Boot clonezilla live
321     <li>Become root by running "sudo su -"
322     <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>
323     cp -r /live/image/lsi /home/partimag
324     <li>cd /home/partimag
325     <li>/opt/drbl/sbin/ocs-live-dev -c -s -i lsi -u lsi -x "ocs_prerun=/live/image/lsi/prep-lsi.sh"
326     <li>/opt/drbl/sbin/ocs-iso -s -i lsi -u lsi -x "ocs_prerun=/live/image/lsi/prep-lsi.sh"
327     <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:
328     <pre>
329     ------------------------
330     #!/bin/bash
331     cp -f /live/image/lsi/megasr.ko /lib/modules/`uname -r`/kernel/drivers/block/

337     </ul>
339     <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>
340     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.

402     live-initramfs - Debian Live initramfs hook
404     Synopsis
405     --------
406     BOOT=live
408     as kernel parameter at boot prompt.
410     Description
411     -----------
413     live-initramfs is a hook for the initramfs-tools, used to generate a initramfs
414     capable to boot live systems, such as those created by *live-helper*(7).
415     This includes the Debian Live isos, netboot tarballs, and usb stick images.
417     At boot time it will look for a (read-only) media containing a "/live"
418     directory where a root filesystems (often a compressed filesystem image like
419     squashfs) is stored. If found, it will create a writable environment, using
420     aufs, for Debian like systems to boot from.
422     You probably do not want to install this package onto a non-live system,
423     although it will do no harm.
425 sng 56 live-initramfs is a fork of <a href="http://packages.ubuntu.com/casper/" target="_blank">casper</a>.
426     casper was originally written by Tollef Fog Heen &amp;lt;tfheen@canonical.com&amp;gt;
427     and Matt Zimmerman &amp;lt;mdz@canonical.com&amp;gt;.
428 sng 28
429     Boot options
430     ------------
432     Here is the complete list of recognized boot parameters by live-initramfs.
434 sng 56 access=*ACCESS*::
435 sng 28
436     Set the accessibility level for physically or visually impared users. ACCESS
437     must be one of v1, v2, v3, m1, or m2. v1=lesser visual impairment, v2=moderate
438     visual impairment, v3=blindness, m1=minor motor difficulties, m2=moderate motor
439     difficulties.
441 sng 56 console=*TTY,SPEED*::
442 sng 28
443     Set the default console to be used with the "live-getty" option. Example:
444     "console=ttyS0,115200"
446 sng 56 debug::
447 sng 28
448     Makes initramfs boot process more verbose.
450 sng 56 fetch=*URL*::
451 sng 28
452     Another form of netboot by downloading a squashfs image from a given url,
453 sng 144 copying to ram and booting it. Due to current limitations in busyboxs wget
454     and DNS resolution, an URL can not contain a hostname but an IP only.
455 sng 28
456 sng 144 Not working: http://example.com/path/to/your_filesystem.squashfs
457     Working:
459     Also note that therefore it's currently not possible to fetch an image from a
460     namebased virtualhost of an httpd if it is sharing the ip with the main httpd
461     instance.
463 sng 56 hostname=*HOSTNAME*, username=*USER*, userfullname=*USERFULLNAME*::
464 sng 28
465     Those parameters lets you override values read from the config file.
467 sng 56 ignore_uuid
468 sng 28
469     Do not check that any UUID embedded in the initramfs matches the discovered
470     medium. live-initramfs may be told to generate a UUID by setting
471     LIVE_GENERATE_UUID=1 when building the initramfs.
473 sng 56 integrity-check::
474 sng 28
475     If specified, an MD5 sum is calculated on the live media during boot and
476     compared to the value found in md5sum.txt found in the root directory of the
477     live media.
481     [DEVICE]:[AUTOCONF]]***::
482 sng 28
483     Let you specify the name(s) and the options of the interface(s) that should be
484     configured at boot time. Do not specify this if you want to use dhcp (default).
485     It will be changed in a future release to mimick official kernel boot param
486     specification (e.g. ip=,:::::eth1:dhcp).
488 sng 144 ip=[**frommedia**]::
489 sng 28
490     If this variable is set, dhcp and static configuration are just skipped and the
491     system will use the (must be) media-preconfigured /etc/network/interfaces
492     instead.
494 sng 56 {keyb|kbd-chooser/method}=**KEYBOARD**, {klayout|console-setup/layoutcode}=**LAYOUT**,
495     {kvariant|console-setup/variantcode}=**VARIANT**, {kmodel|console-setup/modelcode}=
496     **CODE**, koptions=**OPTIONS**::
497 sng 28
498     Configure the running keyboard as specified, if this one misses live-initramfs
499     behaves as if "keyb=us" was specified. It will be interfered from "locale=" if
500     locale is only 2 lowecase letters as a special case. You could also specify
501     console layout, variant, code, and options (no defaults).
503 sng 56 live-getty::
504 sng 28
505     This changes the auto-login on virtual terminals to use the (experimental)
506     live-getty code. With this option set the standard kernel argument "console=" is
507     parsed and if a serial console is specified then live-getty is used to autologin
508     on the serial console.
510 sng 56 {live-media|bootfrom}=**DEVICE**::
511 sng 28
512     If you specify one of this two equivalent forms, live-initramfs will first try
513     to find this device for the "/live" directory where the read-only root
514     filesystem should reside. If it did not find something usable, the normal scan
515     for block devices is performed.
517 sng 144 Instead of specifing an actual device name, the keyword 'removable' can be used
518     to limit the search of acceptable live media to removable type only. Note that
519     if you want to further restrict the media to usb mass storage only, you can use
520     the 'removable-usb' keyword.
522 sng 56 {live-media-encryption|encryption}=**TYPE**::
523 sng 28
524     live-initramfs will mount the encrypted rootfs TYPE, asking the passphrase,
525     useful to build paranoid live systems :-). TYPE supported so far are "aes" for
526     loop-aes encryption type.
528 sng 56 live-media-offset=**BYTES**::
529 sng 28
530     This way you could tell live-initramfs that your image starts at offset BYTES in
531     the above specified or autodiscovered device, this could be useful to hide the
532     Debian Live iso or image inside another iso or image, to create "clean" images.
534 sng 56 live-media-path=**PATH**::
535 sng 28
536     Sets the path to the live filesystem on the medium. By default, it is set to
537     '/live' and you should not change that unless you have customized your media
538     accordingly.
540 sng 56 live-media-timeout=**SECONDS**::
541 sng 28
542     Set the timeout in seconds for the device specified by "live-media=" to become
543     ready before giving up.
545 sng 56 {locale|debian-installer/locale}=**LOCALE**::
546 sng 28
547     Configure the running locale as specified, if not present the live-media rootfs
548     configured locale will be used and if also this one misses live-initramfs behave
549     as "locale=en_US.UTF-8" was specified. If only 2 lowercase letter are specified
550     (like "it"), the "maybe wanted" locale is generated (like en:EN.UTF-8), in this
551     case if also "keyb=" is unspecified is set with those 2 lowercase letters
552     (keyb=us). Beside that facility, only UTF8 locales are supported by
553     live-initramfs.
555 sng 56 module=**NAME**::
556 sng 28
557     Instead of using the default optional file "filesystem.module" (see below)
558     another file could be specified without the extension ".module"; it should be
559     placed on "/live" directory of the live medium.
561 sng 56 netboot[=**nfs**|**cifs**]::
562 sng 28
563     This tells live-initramfs to perform a network mount. The parameter "nfsroot="
564     (with optional "nfsopts="), should specify where is the location of the root
565     filesystem. With no args, will try cifs first, and if it fails nfs.
567 sng 56 nfsopts=::
568 sng 28
569     This lets you specify custom nfs options.
571 sng 56 noautologin::
572 sng 28
573     This parameter disables the automatic terminal login only, not touching gdk/kdm.
575 sng 56 noxautologin::
576 sng 28
577     This parameter disables the automatic login of gdm/kdm only, not touching
578     terminals.
580 sng 56 nofastboot::
581 sng 28
582     This parameter disables the default disabling of filesystem checks in
583     /etc/fstab. If you have static filesystems on your harddisk and you want them to
584     be checked at boot time, use this parameter, otherwise they are skipped.
586 sng 56 nopersistent::
587 sng 28
588     disables the "persistent" feature, useful if the bootloader (like syslinux) has
589     been installed with persistent enabled.
591 sng 56 noprompt
592 sng 28
593 sng 144 Do not prompt to eject the CD or remove the USB flash drive on reboot.
594 sng 28
595 sng 56 nosudo::
596 sng 28
597     This parameter disables the automatic configuration of sudo.
599 sng 56 swapon::
600 sng 28
601     This parameter enables usage of local swap partitions.
603 sng 56 nouser::
604 sng 28
605     This parameter disables the creation of the default user completely.
607 sng 56 noxautoconfig::
608 sng 28
609     This parameter disables Xorg auto-reconfiguration at boot time. This is valuable
610     if you either do the detection on your own, or, if you want to ship a custom,
611     premade xorg.conf in your live system.
613 sng 56 persistent[=nofiles]::
614 sng 28
615     live-initramfs will look for persistent and snapshot partitions or files labeled
616     "live-rw", "home-rw", and files called "live-sn*", "home-sn*" and will try to,
617     in order: mount as /cow the first, mount the second in /home, and just copy the
618     contents of the latter in appropriate locations (snapshots). Snapshots will be
619     tried to be updated on reboot/shutdown. Look at live-snapshot(1) for more
620     informations. If "nofiles" is specified, only filesystems with matching labels
621     will be searched; no filesystems will be traversed looking for archives or image
622     files. This results in shorter boot times.
624 sng 144 persistent-path=PATH
626     live-initramfs will look for persistency files in the root directory of a partition,
627     with this parameter, the path can be configured so that you can have multiple
628     directories on the same partition to store persistency files.
630 sng 56 {preseed/file|file}=**FILE**::
631 sng 28
632     A path to a file present on the rootfs could be used to preseed debconf
633     database.
635 sng 56 package/question=**VALUE**::
636 sng 28
637     All debian installed packages could be preseeded from command-line that way,
638     beware of blanks spaces, they will interfere with parsing, use a preseed file in
639     this case.
641 sng 56 quickreboot::
642 sng 28
643     This option causes live-initramfs to reboot without attempting to eject the
644     media and without asking the user to remove the boot media.
646 sng 56 showmounts::
647 sng 28
648     This parameter will make live-initramfs to show on "/" the ro filesystems
649     (mostly compressed) on "/live". This is not enabled by default because could
650     lead to problems by applications like "mono" which store binary paths on
651     installation.
653 sng 144 silent
655     If you boot with the normal quiet parameter, live-initramfs hides most messages
656     of its own. When adding silent, it hides all.
658 sng 56 textonly
659 sng 28
660     Start up to text-mode shell prompts, disabling the graphical user interface.
662 sng 56 timezone=**TIMEZONE**::
663 sng 28
664     By default, timezone is set to UTC. Using the timezone parameter, you can set it
665     to your local zone, e.g. Europe/Zurich.
667 sng 56 todisk=**DEVICE**::
668 sng 28
669     Adding this parameter, live-initramfs will try to copy the entire read-only
670     media to the specified device before mounting the root filesystem. It probably
671     needs a lot of free space. Subsequent boots should then skip this step and just
672     specify the "live-media=DEVICE" boot parameter with the same DEVICE used this
673     time.
675 sng 56 toram::
676 sng 28
677     Adding this parameter, live-initramfs will try to copy the whole read-only media
678     to the computer's RAM before mounting the root filesystem. This could need a lot
679     of ram, according to the space used by the read-only media.
681 sng 56 union=**aufs**|**unionfs**::
682 sng 28
683     By default, live-initramfs uses aufs. With this parameter, you can switch to
684     unionfs.
686 sng 56 utc=**yes**|**no**::
687 sng 28
688     By default, Debian systems do assume that the hardware clock is set to UTC. You
689     can change or explicitly set it with this parameter.
691 sng 56 xdebconf::
692 sng 28
693     Uses xdebconfigurator, if present on the rootfs, to configure X instead of the
694     standard procedure (experimental).
696 sng 56 xvideomode=**RESOLUTION**::
697 sng 28
698     Doesn't do xorg autodetection, but enforces a given resolution.
700     Files
701     -----
703 sng 56 /etc/live.conf
704 sng 28
705     Some variables can be configured via this config file (inside the live system).
707 sng 56 /live/filesystem.module
708 sng 28
709     This optional file (inside the live media) contains a list of white-space or
710     carriage-return-separated file names corresponding to disk images in the "/live"
711     directory. If this file exists, only images listed here will be merged into the
712     root aufs, and they will be loaded in the order listed here. The first entry
713     in this file will be the "lowest" point in the aufs, and the last file in
714     this list will be on the "top" of the aufs, directly below /cow. Without
715     this file, any images in the "/live" directory are loaded in alphanumeric order.
717 sng 56 /etc/live-persistence.binds
718 sng 28
719     This optional file (which resides in the rootfs system, not in the live media)
720     is used as a list of directories which not need be persistent: ie. their
721     content does not need to survive reboots when using the persistence features.
723     This saves expensive writes and speeds up operations on volatile data such as
724     web caches and temporary files (like e.g. /tmp and .mozilla) which are
725     regenerated each time. This is achieved by bind mounting each listed directory
726     with a tmpfs on the original path.
