move rc_svcdir to /run/openrc on Linux systems
If you are not using linux, this should not affect you. If you are using linux, from this point forward, openrc requires the /run directory to be a mounted tmpfs. If it is, you can run @LIBEXECDIR@/sh/migrate-to-run.sh as root to migrate your dependency tree and state information to the new location. If it is not, you must create the /run directory as root with permissions 755 then reboot your system. reported-by: Maxim Kammerer <mk@dee.su> X-Gentoo-Bug: 401059 X-Gentoo-Bug-URL: https://bugs.gentoo.org/show_bug.cgi?id=401059
