Also, other systems don't make you pre-allocate disk space for snapshot
usage, and other systems don't automatically destroy your snapshot if you
run out of pre-allocated space.  LVM snapshot is crap compared to other
systems - but if you want to make a single snapshot so you can dump or tar
your ext3/4 filesystem in a consistent state or something, then it's good
for that purpose.  And not much else.
