NetBSD (like other Unices) does that for the getty processes on on the
terminals, as defined in /etc/ttys. I have successfully used this
method to start the Xserver automatically and indirectly query the
xdm, so that I get a host chooser instead of the login widget.

The line in /etc/ttys looks like this:

  ttyE4   "/usr/X11R6/bin/X -terminate -indirect boa.home.loc vt05" unknown on

It could probably be used to start (and restart if they terminate)
other processes as well, although I have never tried that. Maybe you
can use one of the pseudo terminals for that.

If you have changed the ttys file, do "kill -HUP 1" to tell init to
re-read the file and, if neccessary, start the programs.
