Yes, it is rather strange that we put any of the UNIX socket paths
under our so called 'lib' directory and not under 'run'. ALl the
UNIX sockets really should be in the same place as the .pid files
as they're not persistent state.  Can't recall why we made this
wierd decision over a decade ago :-)  I'm certainly open to us
correcting this oddity assuming we get the upgrade path right and
selinux policy is likewise ok with it. Neither should be a hard
problem (if any).

With regards,
Daniel
