I'm not sure if this is good systemd syntax, but for mkdir you'd want something like: ExecStartPre=-/bin/mkdir -p -Z $(matchpathcon -n /var/run/foo) /var/run/foo ...but I think "install" does the right thing, so if we know /usr exists it could be: ExecStartPre=-/usr/bin/install /var/run/foo -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
