Well, uninstalls are never elegant, unless we leave them to
good package managers (e.g. Dpkg/Apt) or good version control
systems (e.g. Mercurial).

I personally think it's very elegant not to _need_ any uninstall
stuff. :-)

Is this really a problem? It didn't appear yet, and I doubt it
ever will. Sometimes it happens that some old files are left
around, but these files are simply ignored by the rest of the
system.

Exactly that has been proposed some days ago. Please have a
look at my reply and cosider using that as a starting point
for further discussion:

(simply get that message from the mailing list and hit "reply")


If there's really a problem here, we should course try to
solve it. However, in that case we should first clarify what
the real problem is. What nasty problem would be solved by
some "uninstall" functionality?
