(Adding akonadi-backend-mysql maintainers as recipients) Hi!
When MariaDB Server upgrades, it could trigger a restart in akonadi-backend-mysql, or the maintainer scripts could directly stop the akonadi-backend-mysql. I am open to any solution here. The main question is: what are the expectations from Akonadi on MariaDB upgrades? If MariaDB completely ignores Akonadi, you might run into problems because Akonadi/mysqld did not have a clean shutdown on MariaDB 10.5 and then MariaDB 10.11 will fail to start because crash recovery across major versions. Before going into major version upgrade the old server needs to be stopped gracefully with for example `pkill mysqld` (or a more elaborate version matching other binary names and checking for process owning user etc). If MariaDB stops the server something needs to exist to restart it.
