Oneshot services are possible in runit because you can run a normally downed service with `sv once`.
We can find examples of such services in /etc/init.d/networking (ifupdown) or /etc/init.d/x11-common.
Not really idempotent operations, as opposed to respawns or long running daemons that usually consist
of some idle loop monitoring signals, file descriptors, etc... via system calls like select, poll,
epoll an the like.

Cheers,

Aitor.
