Hello, I do not think so. We introduced these conflicts in exim4-base for dselect's sake in woody->sarge upgrades. Without the conflicts this happened: 1. woody is installed, featuring e.g postfix. 2. user changes sources.list to point to sarge 3. user uses dselect for dist-upgrade. 4. dselect sees a couple of *new* packages of priority important and installs them per default. 5. some of these packages, namely exim4-base{,-config} are completely useless on this system (postfix is up and running.) We introduced the conflicts with all MTA-providing packages in woody to keep dselect from installing exim4-base{,-config} as useless cruft.[1] > Why is conflicting with hula-mta a non-sufficient fix? Because conflicts should be mutual, i.e. every other MTA package would need to conflict additionally with exim4-base. -------------- Policy 3.9 All packages which supply an instance of a common command name (or, in general, filename) should generally use `update-alternatives', so that they may be installed together. If `update-alternatives' is not used, then each package must use `Conflicts' to ensure that other packages *^^^^* are de-installed. -------------- The MTA conflict will also work with unofficial (but policy compliant) MTA packages, a manually set one won't. > I find it a bad idea to have the man pages in two daemon packages. It's just a symlink. [1] The original problem does not exist anymore, woody->sarge is done and sarge->won't suffer from it because exim4-base{,-config} are no more new, unseen packages of priority important for dselect. Therefore these ugly conflicts are imho *cruft* today and I would really like to remove them. -- The 'Galactic Cleaning' policy undertaken by Emperor Zhark is a personal vision of the emperor's, and its inclusion in this work does not constitute tacit approval by the author or the publisher for any such projects, howsoever undertaken.
