It looks like /tmp is not getting the right permissions set (1777).
/etc/fstab:
/dev/md0 /tmp mfs rw,nosuid,nodev,-s=32m,-X 0 0
lizzy:/sbin% ls -li mdmfs mount_mfs
38 -r-xr-xr-x 2 root wheel 342876 Sep 29 14:17 mdmfs
38 -r-xr-xr-x 2 root wheel 342876 Sep 29 14:17 mount_mfs

during bootup shows
getprogname(mfs), compat=0
which explains why it doesn't happen (compat needs to be true). So
getprogname() returns ``mfs'' instead of the expected ``mount_mfs''.
Is this a bug in mount(8) or what? Am I missing something? The manpage clearly
suggests that this should Just Work.
Thanks,
