me too :-) I did something similar some time ago, but using a different approach for testing co-installability: the edos tools. The difference is that this tells you whether it is possible to install by a series of manually guided installations the two packages. This might be the case even if an "apt-get install" query to install the two packages simultanously doesn't find it. OTOH this is still a "local" test specific to one distribution, it does not address the problem of upgrading from an earlier state (dist-upgrading from stable, or partially upgrading some of the packages). As it has been said by Matthew: the missing piece is to properly handle diversions. If you are interested to setup a small project to solve this I'm in. -Ralf. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
