This is where the FHS (Filesystem Hierarchy Standard) and
http://www.lanana.org/ come into play.  The names of executables should be
standardized due to lanana, and file locations should be standardized due to
FHS.  (i.e. an rpm NEVER installs to /usr/local)  There will be edge cases,
but these standards efforts are going forward.

Worse comes to worse, you produce *shim rpms* like the python2-compat that I
built for Mandrake due to the python2 dependancy that c3 had.  These are all
solvable problems, and autoupdate, with auto dependancy tracking, makes a
lot of these go away.

This is a technical problem, and honestly, not that hard of one.  It just
takes some time to think it through.  Just remember... its a technical
problem, therefore it has a solution. :)

There is no silver bullet.  Plus, werewolves make better neighbors than
zombies, and they tend to keep the vampire population down.
