.SH DESCRIPTION
Casper-snapshot is a script useful to build the right types of persistent image files supported by casper, it is also used on exit by the casper init script to resync the boot-found snapshots devices.

.SH OPTIONS
.TP
.BI "\-c, \-\-cow" DIRECTORY
specifies the input directory to be cloned in the image file.
This parameters often does not need to be specified as the default of "/cow" for it 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 casper as home.
.TP
.BI "\-d, \-\-device" DEVICE
the device on where the media which the snapshot/persistence file/partition will be put. If not specified a tmpfs will be used and linked on user's desktop to move it where he/her wants. If the device has not a filesystem on it, an ext2 fs will be created in it and labeled like --output options or with a sane default.
.TP
.BI "\-e, \-\-exclude\-list" FILE
you could pass a list of filenames/path that should not be saved. This exclude list will be remebered on the target snapshotting media for reuse.
.TP
.BI "\-o, \-\-output" FILE
the filename/label to be used for the output file/partition, if left blank it could search for a proper file on the device or use the whole partition.
.TP
.BI "\-r, \-\-resync\-string" STRING
internally used on resyncs.
.TP
.BI "\-t, \-\-type" TYPE
