Briefly: consistency across the various install/uninstall mechanisms.

The "make uninstall" mechanism cleans up (removes) various things, such as
the fifo, in "/var/run"-like locations.  For one example among several see
the "heartbeat/Makefile.am" "uninstall-local:" target.

But the other mechanisms don't have (or don't seem to have) this cleaning
mechanism, so they are left in a dirtier state when the rpm/pkg/whatever
is removed (typically things left lying around in "/var/run"-like
locations).


(The above is about "uninstall".  By analogy, we have similar consistency
issues at install time with owner/group/mode aspects of some special files.)

At the heart of it is that we have to support a variety of different
"install", and therefore by extension "uninstall", mechanisms. This (sadly
not easily resolvable) requires replication of information across those
mechanisms.

To a first approximation, anywhere that our Makefiles say "install-*" or
"uninstall-*" we are likely to need correponding special entries in (or
around) "heartbeat.spec" _and_ in "debian/" _and_ in "pkg/" _and_ in ...
