:-(

For similar reasons I sometimes introduce two profiles for
an add-on product: one (default) that's safe to be applied
again on reinstall and one containing additional settings
which should only be applied on first install. The application
of the latter is then either controlled by a custom
install function (the old 'Extensions.install' thing)
or people are supposed to apply that manually in ZMI using
'portal_setup'.

Of course this is a horrible hack but so far I could live
with it.

In the end we are beaten by the fact that GS has never been
designed to be an installation tool. At least not in the
way we are used to by the quickinstaller.
