	DUNCAN conf is GENERIC but with atapi devs replaced by
	atapicam.
>Description:
	I was happily hacking away, opened another gnome-term
	window and suddenly a couple of nautilus windows popped
	up, along with a couple of dialog boxes that told me
	that it had failed to mount the root partition.

        I hastily ran df to see what had happened (grabbed the
        output below), then unmounted the /media/disk mounts
        with desktop menus.

	duncan [201]$ df -h

	As you can see, this machine has been up for 18 hours or
	so: I can't think of anything that I did directly to
	prompt this activity.
>How-To-Repeat:
	No idea.
>Fix:

	I'm going to re-boot now, just in case badness has
	happened to my /usr and /var partitions...
	I don't know what the implications of having a partition
	mounted r/w at multiple mount points, and through
	multiple device names is...
