Which reminds me: whilst FreeBSD 5.x reminds not-quite-stable-enough for
solid production use (ugh), there is some really nice stuff in it.  I've
played a little with the new UFS snapshots, enough to verify that they
work on a very lightly loaded system, when not kept around for long.

Has anyone tried these UFS snapshots (mksnap_ffs) in anger yet?  Any
information about them at all?

NetApp Filer snapshots rock, but we can't justify NetApp costs for
everything where we want more resilience (customer-facing stuff gets
NetApp with battery-backed write commits, etc, internal stuff often
doesn't).  Has anyone tried FreeBSD 5.x with snapshots and RAID 5?  Any
particular issues?

More long-range, does anyone know if any current projects are working at
bringing undelete() into production stability, as opposed to a
semi-supported 4.4BSD-Lite feature fading into obsolescence?  (_Please_
prove me wrong with that description!)
