I can see the appeal of that, using one-shots to set up the network,
mounts, etc. I don't use s6-rc, but I'll keep it in mind.

However, I realized I've framed the issue incorrectly: I don't care if s6
receives a SIGKILL as long as the supervised processes (including loggers)
have shut down cleanly. I can use elglob/forx/s6-svc -wD to shut everything
down, and just not worry about s6-svscan.
