It will help you to avoid future unpleasant surprises if you take the
time to read up on the Hierarchical File System (HFS) and its relation
the Filesystem Hierarchy Standard (FHS).  The directories /run and
/var/run, which should be the same place on properly configured
systems, are solely to be used for run-time data ONLY.  The phrase
run-time implies ephemeral data that is not preserved between restarts
of the service much less reboots.
