This commit broke my fstab based on ufsid.  I have something like this
in my fstab:

/dev/ufsid/44b3df81873011b5 /    ufs rw,noatime 1 1
/dev/ufsid/463b935456452bbd /tmp ufs rw,noatime 2 2
/dev/ufsid/44b3dfc4bfcc4c30 /usr ufs rw,noatime 2 2
/dev/ufsid/463b934b955f63ff /var ufs rw,noatime 2 2

Mounting / as read-only went fine and I had /dev/ada0s1a,
/dev/ada0s1d, etc.  Strangely, I also had matching ufsid's under
/dev/ufsid, e.g., /dev/ufsid/<some_ufsid>a, /dev/ufsid/<some_ufsid>d,
etc.  However, once I do 'mount -u -w /', everything disappears except
for root's ufsid.

Reverting this commit fixed the problem for me.
