/*
* Tiny test program for the `spawn console' key
* (should not use signal; should not use sleep)
* aeb - 941025
*
* Note: this functionality has become part of init.
*
* Note: open(1) is now part of the `open' Debian package.
*
* You should not use it on a system; if you want to do this,
* be very careful.
*
* If you have this in /etc/rc.local you should
* start getty, not open, or anybody will have a root shell
* with a single keystroke.
