       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
       snapshots devices.


       -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.

       -f, --refresh
           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

       -h, --help
           display help and exit

       -u, --usage
           show usage and exit

       -v, --version
           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.
