readme
dm-merge is a simple tool to apply changes recorded in a copy-on-write
exception table. It can be effectively used to either "commit" the changes into
the source (as made with simple snapshot target) or "rollback" (reverting to a
state the snapshot was created; as made with snapshot linked to snapshot-origin
target). And while LVM snapshots are simply (maybe not so simply, actually) the
latter case, it can revert a logical volume to the exact state it was when the
snapshot was taken.
