Hello,

The weather probably has an effect on me, because I'm not seeing the
cause for the issue below right away. Hopefully someone can use the
cluebat. Also, I apologize if we're not supposed to paste snippets of
this size in email, but I couldn't find a mailing list policy on this.

Some additional information after further debugging:

- The upgrade started at 16:06:18, MariaDB shut down gracefully at 16:06:23, but - while the upgrade was still in progress - started again exactly 5 seconds later at 16:06:28. This makes me suspect a watchdog started MariaDB at the wrong time. However, MariaDB shut down gracefully, so systemd's 'Restart=on-abort' shouldn't have done anything. - The server starts up fine with a new datadir created by 'mysql_install_db'. This confirms the suspicion that the data was corrupted because of *something* that happened during the upgrade

that's why we don't use "mysqld_safe" and don't package "mysql_install_db" as well as we don't restart services at updates in our internal packages

it's simply idiotic doing that within a dist-upgrade and for minor version updates even more
