Good to know.

We cannot push this patch to Linus or -stable. The problem is that will break other things. E.g. login on non-tty0 terminals will break if the distro uses util-linux's login.

con=pts is very nice. UML allocates a pts for each tty on the *host* side. Then you can attach to this tty using screen. See: http://user-mode-linux.sourceforge.net/old/input.html

AFAIK no. But you can tell Fedora to use tty0. Even with systemd this is possible. :-)

Breaking existing applications is a no-go, sorry.
