The old package will remove the symlink generated by alternatives
during %postun unconditionally (also during upgrade). Therefore we
replace the symlink in the new package with a copy of the real file,
alternatives won't touch it and the user is happy.
After some time when everyone ("almost everyone") upgraded, we ship
another update which reverts this ugly hack.
Most likely, we would want the %postun hack to remain for the lifetime of
EPEL-5 (not sure if you want to carry over into EL-6 as well). Other than
that, this looks sane.

I have a series of spec file patches which implement the fix:
Also I built some test scripts which check some
install/uninstall/upgrade procedures. I wrote at least some lines how
to use them in 'how_to_test.txt'.
The tar files there are giving me permission denied but the approach sounds
like it's both worth doing and that you've got a plan that works as well as
anything dealing with replacing symlinks can.
