seems like people do things like this through a preinstall
script, usually [and no, the scriplets typically go inline in
the specfile, not in a separate source pkg].  also done for
appending to /etc/services and other such files.  what bugs me
about these schemes that usually consist of "cat >> somefile" 
is that there's no clean uninstall from that... at least 
conceptually it doesn't seem right that uninstalling any 
given rpm doesn't undo the damage it has done to the system...
