Minimal Getty for Virtual Consoleshttp://www.ibiblio.org/pub/Linux/system/serial/getty/
rungetty might be the getty you were looking for when you want to run any
program, not just login. If a different program than login is used it usually
is run as nobody:nogroup, or the user/group specified on the commandline.
rungetty can even be configured to autologin, under certain circumstances.
See the manual page for more information.
You have to change some lines in /etc/inittab for having any effect after
installing the package. rungetty is based on mingetty and therefore not
suitable for serial use.
