Thanks Peter.

So, it's a shapshot -- is it still usable?  Is it safe to delete it?

snapinfo doesn't know about it:

# snapinfo -v /home
/dev/ad4s2e mounted on /home
         no snapshots found

I'm not in the habit of making snapshots ... but it might have come from a 
dump -L.

Anyway, I think the conclusion is that it's a snapshot, of mysterious 
origin, and it's probably not useful.

Thanks again,
