Subject: [PATCH] multipath-tools: use /run instead of /dev/shm
/dev/shm may have unsafe permissions. Use /run instead.
Use systemd's tmpfiles.d mechanism to create /run/multipath
early during boot.
For backward compatibilty, make the runtime directory configurable
via the "runtimedir" make variable.
