main/openrc-0.42.1-r8 (possibly other versions) exports broken /etc/init.d/runsvdir
openrc package exports the service file
/etc/init.d/runsvdir that has
command=/usr/bin/runsvdir, which openrc does not provide. The
runit package provides both
/sbin/runsvdir files, so even with runit installed, openrc's provided runsvdir service cannot be used out of the box.
I expect either openrc's runsvdir service to be removed, or for openrc to provide runsvdir. I'm biased toward the former solution because I don't think most people are going to think of OpenRC when they want this functionality that runsvdir provides.
