After crash, / comes up mounted read-only, but in multiuser; mfs /tmp?

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.
