At boot time it will look for a (read-only) media containing a "/live"
directory where a root filesystems (often a compressed filesystem image like
squashfs) is stored. If found, it will create a writable environment, using
-unionfs, for Debian like systems to boot from.
+aufs, for Debian like systems to boot from.
You probably do not want to install this package onto a non-live system,
although it will do no harm.
fetch=*URL*::
Another form of netboot by downloading a squashfs image from a given url,

+copying to ram and booting it. Due to current limitations in busyboxs wget
+and DNS resolution, an URL can not contain a hostname but an IP only.

+Not working: http://example.com/path/to/your_filesystem.squashfs
+Working: http://1.2.3.4/path/to/your_filesystem.squashfs
+
+Also note that therefore it's currently not possible to fetch an image from a
+namebased virtualhost of an httpd if it is sharing the ip with the main httpd
+instance.
hostname=*HOSTNAME*, username=*USER*, userfullname=*USERFULLNAME*::
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[=**frommedia**]::
+ ip=[**frommedia**]::
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
filesystem should reside. If it did not find something usable, the normal scan
for block devices is performed.
+Instead of specifing an actual device name, the keyword 'removable' can be used
+to limit the search of acceptable live media to removable type only. Note that
+if you want to further restrict the media to usb mass storage only, you can use
+the 'removable-usb' keyword.
+
{live-media-encryption|encryption}=**TYPE**::
live-initramfs will mount the encrypted rootfs TYPE, asking the passphrase,
disables the "persistent" feature, useful if the bootloader (like syslinux) has
been installed with persistent enabled.
+ noprompt
+
+Do not prompt to eject the CD or remove the USB flash drive on reboot.

This parameter disables the automatic configuration of sudo.

+ swapon::
-This parameter disables usage of local swap partitions.

if you either do the detection on your own, or, if you want to ship a custom,
premade xorg.conf in your live system.
- persistent::
+ persistent[=nofiles]::
live-initramfs 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.
+
+ persistent-path=PATH
+
+live-initramfs 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.
{preseed/file|file}=**FILE**::
lead to problems by applications like "mono" which store binary paths on
installation.
+ silent
+
+If you boot with the normal quiet parameter, live-initramfs hides most messages
+of its own. When adding silent, it hides all.

Start up to text-mode shell prompts, disabling the graphical user interface.
to the computer's RAM before mounting the root filesystem. This could need a lot
of ram, according to the space used by the read-only media.

-By default, live-initramfs uses unionfs. With this parameter, you can switch to
-aufs.

utc=**yes**|**no**::
This optional file (inside the live media) contains a list of white-space or
carriage-return-separated file names corresponding to disk images in the "/live"
directory. If this file exists, only images listed here will be merged into the
-root unionfs, and they will be loaded in the order listed here. The first entry
-in this file will be the "lowest" point in the unionfs, and the last file in
-this list will be on the "top" of the unionfs, directly below /cow. Without

this file, any images in the "/live" directory are loaded in alphanumeric order.
+ /etc/live-persistence.binds
+
+This optional file (which resides in the rootfs system, not in the live media)
+is used as a list of directories which not need be persistent: ie. their
+content does not need to survive reboots when using the persistence features.
+
+This saves expensive writes and speeds up operations on volatile data such as
+web caches and temporary files (like e.g. /tmp and .mozilla) which are
+regenerated each time. This is achieved by bind mounting each listed directory
+with a tmpfs on the original path.
