* Tiny test program for the `spawn console' key

*
* Note: this functionality will probably go away and become
* part of init. For the time being, be very careful when
* you use this - if you have this in /etc/rc.local you should
* start getty, not openvt, or anybody will have a root shell
* with a single keystroke.
