As gentoo switched to /var/run/ -> /run in tmpfs recently
people got into problems [1] of missing directories like:
/var/run/screen/
/var/run/openfire/
/var/run/proftpd/
they did bite me personally.
openrc-0.10 brought [2] basic support for systemd's tmpfiles'd:
http://0pointer.de/public/systemd-man/tmpfiles.d.html
But there is no simple way to install such helpers from ebuilds.
The tmpfiles.d is aimed to help in such situations.
I've picked proftpd as an example as it's situation is very similar
to screen's situation. There is inetd mode (opposed to standalone
mode) when you don't have any init.d code to create /var/run/
directories for you. Thus tmpfiles.d for the rescue.
See attach for the whole eclass code. It's almost a copy of Micha=C5=82's
bash-completion-r1.eclass which I find very easy to use.
I'll show eclass usage example for proftpd:

The caveats:
- files get created only if I run /lib/rc/sh/tmpfiles.sh manually
- haven't tested with systemd, but i'd expect it to work
Thanks!
