Description Charlie & 2008-03-17 11:50:01 UTC 
snapinfo only works for top level mount points:

 mount | grep opt
/dev/ar0s1e on /opt (ufs, local, soft-updates, acls)

# : snapinfo -a
/.snap/daily.0
/.snap/weekly.0
/var/.snap/hourly.3
/var/.snap/hourly.2
/var/.snap/hourly.1
/var/.snap/hourly.0
/opt/.snap/weekly.0
/opt/.snap/daily.5
/opt/.snap/daily.4
/opt/.snap/daily.3
/opt/.snap/hourly.7
/opt/.snap/hourly.6
/opt/.snap/hourly.5
/opt/.snap/daily.1
/opt/.snap/hourly.4
/opt/.snap/hourly.3
/opt/.snap/hourly.2
/opt/.snap/hourly.1
/opt/.snap/daily.0
/opt/.snap/hourly.0

But if you mount a fs e.g. in /mnt like in FreeNAS or KDE snapinfo fails:

 mount | grep opt
/dev/ar0s1e on /mnt/opt (ufs, local, soft-updates, acls)

168914 : snapinfo -a
/.snap/daily.0
/.snap/weekly.0
/var/.snap/hourly.3
/var/.snap/hourly.2
/var/.snap/hourly.1
/var/.snap/hourly.0
ufs_disk_fillout: Unknown error: 0

This prevents using snapshots in this case. I've not fully analyzed if this
also hits the snapshot tools http://people.freebsd.org/~rse/snapshot/.
