What happens on runit, I can't speak for the others, is that there is a
process 1, called as init by the kernel at start up. If init fails
you're screwed, but that's true of every other init. Init starts, and
will respawn if necessary, runsvdir, that actually starts the monitoring
processes. Each service has a monitoring runsv process that restarts
the service if it fails, ditto for the log processes.
I wouldn't implement it on belg, too much of a revolution, but I think
some kind of process supervision is a necessary part of a high
You can run runit under init, BTW, so it can be tried out without too
much commitment - in which case it's like daemontools without the
(expletive deleted) Bernstein.
