But then you end up with an unsupervised runsv process, disconnected
from the rest of the supervision tree...

However, regarding Void Linux and udevd, as far as I can tell by
having a quick look at their GitHub repository, it is launched
unsupervised from /etc/runit/1 just to populate /dev, but then that
process is stopped using 'udevadm control --exit', and a supervised
one is launched. Probably the best possible solution if constrained by
the runit model...
