Aha! <http://cygwin.com/ml/cygwin/2005-07/msg00337.html> -- that's what's been nagging at me all that time. The reason you have to use the preremove script instead of relying on the postinstall one is that there may not *be* a postinstall script that does the right thing (for example, when downgrading). FWIW, I still see nothing wrong with a preremove script.
