Then it should also need separate binaries, libraries, datadir, socket, ... I'm not saying it is so bad idea, but it could be taken into account only in the upstream, we really cannot do something like that downstream. And we'd probably lost the drop-in feature and upgrade would be even more painful.

How so?

If fesco does not ban mysql from the distribution then upgrades should not be painful because you would simply upgrade to the latest mysql release in the distribution.

If mysql on the other hand is banned in the distribution then arguably it makes sense to migrate those instances to the latest release of mariadb instead thou I personally would not recommended it then either but rather prefer it would be left alone then replaced by admin himself after upgrade.

In case it would be discussed, compatible, documented, noted in the release notes and we have a good reason to do so -- then why not?


Different product different characteristics

If you install mate or cinnamon or unity for that matter would you
expect to be migrated and running Gnome 3.x after upgrade or would you
expect to be continuing to use and run what got forked or based of it.

This is already too extreme, we cannot compare Gnome forks and MySQL forks. It's really a different scenario.

Same fundamental rules apply as I see it just different ( fork ) components.


One usage scenario one simple question

If an user wants to run both those database solution on his server wont
those two overlap as in can for exaxmple users be asssured that the
changes that they make to their my.cnf wont get picked up by mariadb
when it gets started etc.

Running both packages on the same server is not currently available, because they conflict. If somebody does it in any way, which means to separate files, sockets, ... then he should be able to separate config files as well.

Is that not an clear indicator that the replacement should not take place on upgrade but rather be left up to the administrator to do manually ( at least while we still ship mysql ) and we have mysql and mariadb conflict with each other on packaging level?
