If that's the real reason it broke, then the scheme Peter was saying
wouldn't work (which really meant "wouldn't work on his system", since
login shells that are not children of "init" work fine on other
systems) *would* work - "ct" can most definitely arrange that the
process it forks off to run "getty" becomes the leader of the process
group that owns the terminal.  In fact, it does precisely that; before
"exec"ing "getty", it calls "setpgrp".
