[debian-mysql] Bug#966196: mariadb-server-10.3: Mariadb 10.3.22 fails to start after Stretch update, Failed at step EXEC spawning /etc/mysql/debian-start: No such file or directory

[elvis]

Package: mariadb-server-10.3
Version: 1:10.3.22-0+deb10u1
Severity: normal

Dear Maintainer,

After updating Stretch mariadb fails with 

Jul 25 01:19:38 dog systemd[23576]: mariadb.service: Failed at step EXEC spawning /etc/mysql/debian-start: No such file or directory
Jul 25 01:19:38 dog systemd[1]: mariadb.service: Control process exited, code=exited, status=203/EXEC
Jul 25 01:19:40 dog systemd[1]: mariadb.service: Failed with result 'exit-code'.
Jul 25 01:19:40 dog systemd[1]: Failed to start MariaDB 10.3.22 database server.


The file debian-start actually has some text inside it saying this file is no longer needed, I deleted it once and got the same error. 
I recreated it and it all worked again.
It seems to have vanished after the update bringing the same situation back.

A workaround is to create the file.
