live-snapshot - a simple script to ease persistence usage

live-snapshot is a script which can be used to build the right types of
persistent image files supported by live-initramfs(7). It is also used
on exit by the live-initramfs init script to resync the boot-found
-c, --cow DIRECTORY
specifies the input directory to be cloned in the image file. Its
default value "/live/cow" should be right for most uses. However it
could be handy to specify "/home" and type ext2 for the type to
prepare an image file suited to be directly mounted by
live-initramfs as home.
-d, --device DEVICE
sets the device where the media which the snapshot/persistence
file/partition will be put. If it is not specified, a tmpfs will be
used and linked to the user’s desktop to move it where it is
needed. If the device has no filesystem, an ext2 fs will be
automatically created and labelled according to the values
specified after the "--output" value or with a sane default.
-e, --exclude-list FILE
a file containing a list of filenames/paths that should not be
saved. This exclude list will be remebered on the target snapshot
media for reuse.
-o, --output FILE
the filename/label used for the output file/partition. If left
blank, live-snapshot will search for a proper file on the device or
use the whole partition.
-r, --resync-string STRING
internally used on resyncs.
try to do the same operation that should be done at reboot or halt,
resyncing boot-time auto discovered snapshots. Useful to prevent a
crash or surge power-off.
-t, --type TYPE
Type could be one of "cpio", "squashfs", "ext2", "ext3", "ext4", or
display help and exit
show usage and exit
output version information and exit
This optional file, if present changes the behaviour of live-snapshot,
only files and directories listed there are included (integrally) in
the snapshot. It works only for cpio and whole partition targets.
This optional file, if present will filter the files that will be saved
by live-snapshot removing (as in "grep -F -v") all filenames that will
be matched by strings listed in it. It works for cpio, whole partition
and squashfs snapshot types only; it is pretty useful for filtering
temporary files and disk caches.
This program is a part of live-initramfs.
