Er, what is the mount(..., MNT_RELOAD ...) in tunefs for then?  Unmounting
and remounting should not be necessary for any read-only file system
including "/".  You can do the MNT_RELOAD from the command line using
mount -u if tunefs doesn't do it.

I have some old fixes for tunefs which fix missing remounts as a side
effect.  In -current, tunefs only detects mounted filesystems if they
are in fstab.  It clobbers read-write mounted filesystems and fails to
remount read-only mounted file systems if they are not detected.
