The only way this could happen is to add a manifest of installed files, in order to allow uninstallation and upgrades to be made safe in the absence of a packaging system. The .egg file/directory technique currently makes uninstallation as simple as "rm -rf package-version.egg", and multi-version installs work with no special action. Note, too, that using .egg files or directories means that installation *never breaks existing programs* as long as they have specified their dependencies accurately. Traditional distutils installation is destructive in the absence of a system packager. However, if you *have* a system packager, then you should not be using "setup.py install" anyway, so I'm not sure I see how this is an issue. You should be simply building system packages. And it's quite straightforward to make most bdist_* commands work: bdist_wininst and bdist_dumb work with setuptools "out of the box" because they call the "install" command internally; only bdist_rpm required some monkeypatching to add --single-version-externally-managed, because it writes script files that run "install" later. Anyway, I guess what I'm saying is, if you want traditional distutils-style installation, you should use system packages, since they're the only way to allow uninstallation and avoid corrupted upgrades. Otherwise, you should use .egg files or directories, in which case easy_install (and in the future, nest) will be your package manager. _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
