Killing the automount would also fix a lot of the other problems as you
can then mount it in the initrd and dump it when you have the real fs up,
or you can mount it privately thanks to Al Viro's magic with mount points
and only the daemon that must make the "real" device file system need
have it mounted and accessible.

Thats a good thing - it stops some of the suprise behaviour the Eric
pointed out and objected to.

And I think btw the underlying failure was in the tty layer - I just need
to find it. It's the second report vaguely of this form so something is
lurking in the stygian depths.
