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

There are many directories already in Fedora that are not defined by FHS
and even though we have asked them to update it  (libexec,  /selinux 
/sys etc),  there is noone maintaining it.    Besides,  FHS violations
do not qualify as release blockers at all.  At best,  this is a dramatic
overreaction and wishful thinking.   If we have consensus between major
distributions,  that is the living standard compared to a old stale and
unmaintained document.   Anyway,  thanks Lennart for taking the time to
explain the change.  It makes documentation much easier.
