What's this /run directory doing on my system and where does it come from?

While I've agreed with the need for /run, I think that the definition of
application that you are using here is a more recent (and not universally
adopted) differentiation from "program" than what existed in the FHS.  We
could try to contact Rusty Russell (who's posted something about /run here:
https://lwn.net/Articles/436177/ ) to see if the terms application and
program should be considered synonymous in the FHS or if they denote two
separate things.  Since the purpose of the FHS is to define interoperability
between distributions and properly set the expectations of system
administrators, however, the broader interpretation of application as
synonymous with program is probably the better one until/unless an updated
FHS defines the terms explicitly.
