There is no such guarantee. A user might have customized the mysql service to look somewhere else for configuration, for example, but some clients may still look in /etc/mysql, find nothing, and continue as normal. Re-adding /etc/mysql with a different configuration would break that arrangement, and a user affected like that could quite rightly complain that special casing MySQL packaging against established packaging policy was surprising and wrong. There are other (not-MySQL) cases where removing a file from /etc does correctly adjust a service rather than completely break it (for example as a mechanism to switch to upstream defaults rather than packaging defaults). We cannot both deal with this special case and also behave correctly for other users who expect the general rules to be followed. > What the package maintainers seem to be saying is "hey, too bad your > attempts to fix bad config went wrong and you decided to start again, we > won't help you at all." I have no objection to heuristic detection and pointing users to a solution, if you want implement and contribute that. For example, this could detect the situation and print a message along the lines of "if you deleted /etc/mysql in the hope of restoring defaults, actually you need to purge the packages and reinstall them". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1579708 Title: mysql maintainer scripts fail if files in /etc/mysql have been deleted locally To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/1579708/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
