I'm afraid I can't help with the specifics immediately (I'll need
to set up some NFS mounts), but some general comments about the
- if you mount a filesystem with the "user" option, the user who
mounted it will be written to /run/mount/utab. While I've not
tested this for NFS, it's certainly the case for all other mounts.
- when umounting a filesystem, the content of /etc/fstab should be
irrelevant. The information needed is in /etc/mtab (/proc/mounts)
and /run/mount/utab. If the NFS mount helpers are using fstab
during umount, I think that's a separate bug in its own right.
- the trailing / may be an issue. Does the entry (if any) in
/run/mount/utab match this? Does adding a trailing / to the
umount command affect things?
