Yep, that's what I found. mount -o rw no longer works only -w.
Interestingly '-o rw' is not in the manpage, which is how I originally
discovered that '-w' was working. One script in rc.d appears to use it.
However I think it would be better to fix the mount options they way they
were. I noticed also that if you go multi-user after a crash, you'll get
the mfs mounts noted above and in addition the only way to mount / is to
reboot. Dropping to single user and attempting to mount -w after the fsck
completes complains about invalid argument or invalid device /dev/ad0s1a.
