Typically, these per-service dirs in /run/ get recreated during
restart, by the service in question. In addition, if RuntimeDirectory=
is used in the service, systemd will automatically clear the specified
directory when a service goes down. It's generally assumed to be the
job of the daemon in question to create and make sure things are
properly owned on next start if it uses different users and drops
privs on its own.
