.SH NAME
\fBlive\-boot\fR \- System Boot Scripts
.SH CONFIGURATION
\fBlive\-boot\fR can be configured through a boot parameter or a configuration file.
+.PP
+To configure the live\-boot parameters used by default in a live image, see the \-\-bootappend\-live option in the \fIlb_config\fR(1) manual page.
.SS Kernel Parameters
\fBlive\-boot\fR is only activated if 'boot=live' was used as a kernel parameter.
In addition, there are some more boot parameters to influence the behaviour, see below.
.SS Configuration Files
-\fBlive\-boot\fR can be configured (but not activated) through configuration files. Those files can be placed either in the root filesystem itself (/etc/live/boot.conf, /etc/live/boot.conf.d/), or on the live media (live/boot.conf, live/boot.conf.d/).
+\fBlive\-boot\fR can be configured (but not activated) through configuration files. Those files can be placed either in the root filesystem itself (/etc/live/boot.conf, /etc/live/boot.d/), or on the live media (live/boot.conf, live/boot.d/).
.SH OPTIONS
\fBlive\-boot\fR currently features the following parameters.
Do not check that any UUID embedded in the initramfs matches the discovered medium. live\-boot may be told to generate a UUID by setting LIVE_GENERATE_UUID=1 when building the initramfs.
.IP "\fBintegrity\-check\fR" 4
If specified, an MD5 sum is calculated on the live media during boot and compared to the value found in md5sum.txt found in the root directory of the live media.

Let you specify the name(s) and the options of the interface(s) that should be configured at boot time. Do not specify this if you want to use dhcp (default). It will be changed in a future release to mimick official kernel boot param specification (e.g. ip=10.0.0.1::10.0.0.254:255.255.255.0::eth0,:::::eth1:dhcp).
.IP "\fBip\fR=[\fIfrommedia\fR]" 4
If this variable is set, dhcp and static configuration are just skipped and the system will use the (must be) media\-preconfigured /etc/network/interfaces instead.
disables the "persistent" feature, useful if the bootloader (like syslinux) has been installed with persistent enabled.
.IP "\fBnoprompt\fR" 4
Do not prompt to eject the CD or remove the USB flash drive on reboot.
+.IP "\fBnoprompt\fR=\fITYPE\fR" 4
+This tells live-boot not to prompt to eject the CD (when noprompt=cd) or remove the USB flash drive (when noprompt=usb) on reboot.
+.IP "\fBramdisk\-size\fR" 4
+This parameters allows to set a custom ramdisk size (it's the '\-o size' option of tmpfs mount). By default, there is no ramdisk size set, so the default of mount applies (currently 50% of available RAM). Note that this option has no currently no effect when booting with toram.
.IP "\fBswapon\fR" 4
This parameter enables usage of local swap partitions.
-.IP "\fBpersistent\fR[=nofiles]" 4
-live\-boot will look for persistent and snapshot partitions or files labeled "live\-rw", "home\-rw", and files called "live\-sn*", "home\-sn*" and will try to, in order: mount as /cow the first, mount the second in /home, and just copy the contents of the latter in appropriate locations (snapshots). Snapshots will be tried to be updated on reboot/shutdown. Look at live\-snapshot(1) for more informations. If "nofiles" is specified, only filesystems with matching labels will be searched; no filesystems will be traversed looking for archives or image files. This results in shorter boot times.
+.IP "\fBpersistent\fR" 4
+live\-boot will probe filesystems for persistent media. These can either be the filesystems themselves, if labeled correctly, or image/archive files, if named correctly. Overlays are labeled/named either "live\-rw" or "home\-rw" and will be mounted on / or /home, respectively; snapshots are labeled/named either "live\-sn" or "home\-sn" and will be extracted into / or /home, respectively (see live\-snapshot(1) for more information). Overlays are mounted before snapshots are extracted, and for both overlays and snapshots, "live\-*" are handled before "home\-*". Overlay image files and snapshot archive files have extensions which determines their filesystem or archive type, e.g. "live\-rw.ext3" and "\home\-sn.squashfs".
+.IP "\fBpersistent\-encryption\fR=\fITYPE1\fR,\fITYPE2\fR ... \fITYPEn\fR" 4
+This option determines which types of encryption that we allow to be used when probing devices for persistent media. If "none" is in the list, we allow unencrypted media; if "luks" is in the list, we allow LUKS\-encrypted media. Whenever a device containing encrypted media is probed the user will be prompted for the passphrase. The default value is "none".
+.IP "\fBpersistent\-media\fR={\fIremovable\fR|\fIremovable\-usb\fR}" 4
+If you specify the keyword 'removable', live\-boot will try to find persistent and snapshot partitions on removable media only. Note that if you want to further restrict the media to usb mass storage only, you can use the 'removable\-usb' keyword.
+.IP "\fBpersistent\-method\fR=\fITYPE1\fR,\fITYPE2\fR ... \fITYPEn\fR" 4
+This option determines which types of persistent media we allow. If "overlay" is in the list, we consider overlays (i.e. "live\-rw" and "home\-rw"); if "snapshot" is in the list, we consider snapshots (i.e. "live\-sn" and "home\-sn"). The default is "overlay,snapshot".
.IP "\fBpersistent\-path\fR=\fIPATH\fR" 4
live\-boot will look for persistency files in the root directory of a partition, with this parameter, the path can be configured so that you can have multiple directories on the same partition to store persistency files.
+.IP "\fBpersistent\-read\-only\fR" 4
+Filesystem changes are not saved back to persistent media. In particular, overlays and netboot NFS mounts are mounted read-only, and snapshots are not resynced on shutdown.
+.IP "\fBpersistent\-storage\fR=\fITYPE1\fR,\fITYPE2\fR ... \fITYPEn\fR" 4
+This option determines which types of persistent storage to consider when probing for persistent media. If "filesystem" is in the list, filesystems with matching labels will be used; if "file" is in the list, all filesystems will be probed for archives and image files with matching filenames. The default is "file,filesystem".
+.IP "\fBpersistent\-subtext\fR=\fISUFFIX\fR" 4
+Add a suffix when searching for the image filenames or partition labels to use for the above mentioned persistent feature, the SUFFIX will be added after a dash (e.g.: "live-sn" would transform to "live-sn-SUFFIX"). This is handy to test multiple live-boot based live-systems with different persistent storage choices.
.IP "{\fBpreseed/file\fR|\fBfile\fR}=\fIFILE\fR" 4
A path to a file present on the rootfs could be used to preseed debconf database.
