Hello,
The netfs scripts for Red Hat go through and umount any loopback devices
before attempting to umount the encompassing filesystem. This seems a sane
thing to do (and I have a bug on said issue), so I've added similar
functionality to the autofs init script. Attached is a patch. Comments
encouraged. Testing by debian folks would be nice, too.
