Would it make sense for s6-supervise to inform s6-svscan of its
child process ID? If s6-svscan is PID 1 and s6-supervise dies,
the child will be reparented to s6-svscan. s6-svscan could then
wait for it to exit before spawning s6-supervise again.
This works very nicely with PID namespaces, as it ensures that
every process in the PID namespace has exited before the service
can be respawned. It works without PID namespaces as well, though.
If this is a good idea I might be able to submit a patch, but the
first step is to know if this is something upstream is interested
in.
