[NBLUG/talk] Why have directories in /var/run if they're not persistent through reboot?

A little birdie told me the electrons on #nblug self-rearranged, thus:


00:42 < redrick> Yes, /var/run is volatile these days (tmpfs), but that's fine
                 because it's supposed to be volatile program state for
                 currently running programs.  When the system reboots (the only
                 time normally that the 'volatile' aspect of a tmpfs should
                 come into play), it's totally appropriate that the entirety of
                 /var/run go away, because all the running programs did, too.

00:42 < redrick> /var/run is very unlikely to be 'lost' except by reboot, and
                 then it _should_ get lost, is what I'm saying.
00:44 < redrick> As to the subdirs under /var/run, FHS has rationale.

00:45 < redrick> That help?
