This is a program you can use to automatically log in on a workstation when
it boots.  Look for a line in /etc/inittab that looks like this:

1:2345:respawn:/sbin/mingetty tty1

Replace it with this:

1:2345:respawn:/sbin/autlogin tty1 joeuser

And joeuser will be logged in automatically when the system boots.  To have
some command other than a shell started, supply it as a third argument:

1:2345:respawn:/sbin/autlogin tty1 joeuser startx

Note that this is a potential security risk that's big enough to drive a truck
through, and it's only guaranteed to work with pam_unix and possibly pam_pwdb.

Consider yourself warned.
