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 ... -- : David Lee I.T.
