Including local filesystems that aren't exported?

If so, that's interesting because I do that in my weekly periodic cron
job. It's a simple script that umounts a backup partition, newfs's it,
dumps a local copy of /home over to it, and then re-mounts it (for easy
user-accessible near-line backup storage that doesn't require going to
tape for the "real" backup).
