Hi Matthias and everybody, on my side I agree that self-contained priority levels are not needed anymore and are even becoming harmful. This said, there were objections to the removal of this rule in this thread and in #759260, and I do not remember if we had good answers to each of them. Matthias, do you think that you could make a summary of the pros and cons that were discussed in these threads ? Regarding your proposed change, I wonder what is the practical case for forbidding conflicts with higher-priority packages. Could you give an example showing that it is strictly necessary ? Otherwise, it would be simpler to simply remove the requirement for adjusting priorities. Lastly, while we are at it, let's insert a clarification that in Debian, the priority of the packages are determined by the archive administrators, and that the source package control file is not the canonical source of information for a binary package's priority when this package is distributed in the Debian archive. (This would close #616055). Have a nice day, -- Charles Plessy Tsurumi, Kanagawa, Japan -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
