They are mounted and they have to be mounted (at least here). If
they weren't mounted, people couldn't access them. That's why
they are also being traversed by 310.locate and 340.noid. To
summarise:

- I use UFS.
- My snapshots must be mounted.
- They are being traversed by 310.locate and 340.noid.
- I don't want the latter.

To accomplish this, I can play around with (directory name dependent)
exclusion lists for 310.locate and 340.noid. I could also implement
a rdonly knob.
