That's part of the whole reason -R exists (now). You could have
gotten yourself into a worse mess if you'd been using symbolic links
like I used to - IIRC, mount would mount on the symlink but umount
would resolve it before passing it through.
:It does worry me though that the system panicked when shutting down
:(when the mount_union was still in place).
:Should this be pr'ed? I guess the first thing to do is upgrade to
:BETA and see what happens there.
The union fs is not stable - it's buggy and known to be (well, at least
by some of us who use it regularly) though it's quite a bit better than
it was a couple of years ago. I have two sets of union mounts on
one machine: one is a union mount of a RW FFS above a RO cdrom
and I have zero problems with it. The other is a RW FFS above another
RW FFS and I have problems with that sometimes if I don't umount it
(Of course, I've got other issues with reboot now not unmounting cleaning
arising from some update within the last couple of weeks.)
