 Can anyone think of more suggestions?  I'm trying to use these

 I'd appreciate any suggestions.

Google for ttysnoop.

Screen can definitely attach to a virtual console.  I just tried the
following in /etc/inittab:

c5:2345:respawn:/usr/bin/screen -R tty5.localhost /bin/login

/dev/tty5 /dev/tty5 21

c6:2345:respawn:/usr/bin/screen -R tty6.localhost /bin/login

/dev/tty6 /dev/tty6 21


You can then attach to either of those with

screen -D -r tty5.localhost
screen -D -r tty6.localhost

The only thing you really can't do is login as root, because screen
uses psuedo tty's which are declared unsecure by default.  Unless you
want to add all pty devices to /etc/securetty...

But there is no security with this setup anyway, because on a console
all one has to do is Ctrl-a c to get a root shell.

Still, this should give you an idea of what you will have to do if you
are going to write your own program to manage this...
