Thanks for the response Keith, but I've got a firm grip on these aspects
of the problem.

What I don't have a firm grip on, is upon digging up a list of local
filesystems, how do I then rsync all the files in those filesystems with a
single rsync command?  Or at least, how I can do it with at most one
password entry, so I don't have to come back and reauthenticate for each
filesystem?

My first thought was to just list all of the mount points, but then some
of those directories will have NFS mounts under them, making
--one-file-system advantageous, but if I give a list of mount points
to rsync, then it appears that it doesn't want to sync a single
file.  :-S

Thanks!
