Comment:
Actually this should be kinda fixed. 
Major upgrades require that people manually stop mysql/mariadb and run `mysql_upgrade`, which is clearly documented from upstream. The INSTALL script was changed to not install the initial db that often.

Stopping and running `mysql_upgrade` automatically could imo cause more harm than good.
