There are a couple approaches you can take:
One simpler would be to use a cron job that runs @reboot
I believe these cron jobs would be run after the system is booted in
multiuser. You could experiment to determine if this is the case.
An alternative which would be more complex would be to write an rc script
that runs from /usr/local/etc/rc.d. Such a script would need to support at
least the standard parameters of:
You can easily add:
where the restart function calls the stop and then the start functions.
In the start function if you need to verify a getty running, you can do:
ps -ax|grep getty
to see if it is 0 and a getty is found, or that it is 1 and the getty is
