That's unfortunately not true: by default (wo any --prefix option), distutils install into /usr. So if a user just uses sudo with a distutils-based package, he is very likely to mess up his system. I think this should be considered as a distutils bug - by default, most source distributions install into /usr/local (autoconf-based projects certainly do). > How should such a system stop distutils (acting as root) from doing an > uninstallation? > Ideally, distutils should detect whether it installed the package itself or not. IMHO, uninstall is beyond the scope of distutils; it is very difficult to get right, with so many ways to screw up a system badly. cheers, David _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
