/* VAR_RUN is where pid and socket files used for communicating
* with mdmon normally live. It should be /var/run, but if
* it is too hard to remount /var/run as read-only rather than
* unmounting it at shutdown time, then it should be
* redefined to some place that comfortably persists until
* final shutdown, possibly in /dev if that is a tmpfs.
* Note: VAR_RUN does not need to be writable at shutdown,
* only during boot when "mdmon --takeover" is run.
