[PATCH] Systemd start after upgrade from MySQL 5.6 to MariaDB 10.0 does not work on Sid, Vivid, Wily

Description

After had been fixed and the bugfix backported to 10.0, upgrade from MySQL 5.6 to 10.0 on Sid, Vivid, Wily is able to proceed further: the packages are installed all right, but the server does not start after upgrade.

If /etc/init.d/mysql start is run manually, it exits with zero code immediately without any messages, MariaDB is not started. Nothing in the logs.

As far as I could tell, the following happens.

  • /etc/init.d/mysql at the very beginning calls /lib/lsb/init-functions

  • /lib/lsb/init-functions triggers some hooks, one of which is /lib/lsb/init-functions.d/40-systemd

  • /lib/lsb/init-functions.d/40-systemd checks the status for service mysql.service, and if it finds LoadState=masked, it exits, silently and without errors.

Apparently, the status is exactly that after MySQL 5.6 is uninstalled.

I don't really know what can be done about it. If we don't support crossgrade from MySQL 5.6 to 10.0, so be it – it's not so very important since we already have 10.1 and it works; but then we should make the decision and disable the test in buildbot.
