tmpfiles.d is from systemd:

http://www.freedesktop.org/software/systemd/man/tmpfiles.d.html

However, I think OpenRC developers were thinking about supporting it.
I don't know if that actually happened.

With systemd in Gentoo, /var/run is bind mounted from /run, and it's a
tmpfs dir, so everything there goes away after a reboot. The config
files in tmpfiles.d allows the creation (and automatic removal) of
directories and files there.

I don't know if it's the "correct" way to fix anything; but it works.
