# Yes, there are difficulties, depending on the name of the volume.

/dev/vinum/Ports in this case.

# Hmm.  I haven't tried this.  It works fine with -t ufs, at least on

Yes. On -CURRENT -T ufs: only works when /etc/fstab already has an entry
for /dev/vinum/Ports.

Starting without an entry in /etc/fstab:

Hmm. The last usage message looks suspicious. Is something wrong with
fsck's option parsing or passing to fsck_ufs?

Thanks for any input, and, before it's over, happy new year!
