How can I get amanda dumps to use snapshoting?  Freebsd with the 5.0
release can now snapshot its file systems.  This is great for getting
more consistant image to dump.  When amanda is doing actual dumps (as
apposed to asking for estimated tape lengths etc) it should add the -L
switch to dump.  This makes freebsd take a snapshot, dump the snapshot,
then release the snaphot.

Before I look into the amanda sources to add this, I was wondering if
anyone had done it already?
