I like this, but I think it would be better done in a panic_notifier.

I didn't do it this way on purpose.  I create an internal procfs mount in
case the UML root user has mounted something else on /proc.  I don't want
the mconsole on the host to be faked out by that.

Applied, BTW, this one is mangled on your site:
	@@ -129,6 +129,7 @@ static int uml_net_open(struct net_devic

It's in my 2.4 tree and will get moved over to 2.6 in due course.

I like this one, but it's big and I'm going to have to take a good look at it.
I'm somewhat unhappy about the command line change, where you need to specify
a console or UML doesn't boot.  That'll break everyone's scripts.  Is it 
possible to provide a default console if there isn't one on the command line?

It's stuck on 2.6.4 for now.  I'm going to get it caught up, but haven't
decided when yet.
