An excellent and very apropos point.

In theory, I might be able to use cpio -p rather than rsync to make my
backups, however for some reason that I can't remember anymore, when
I originally set up my system for making backups, I looked at that
possibility and concluded that rsync was preferable to cpio -p.  I
wish that I could remember why.  (It might have had to do with better
or more complete handling of ``weird stuff'' like extended file
attributes, ACLs, device nodes, or other such oddities)

No, actually.  thanks for the suggestion!

The diff I have here on FreeBSD (9.1) seem to be GNU, so this will work.
