[debian-mysql] Upgrade of mariadb

[Vermeulen Jean]

I need to use directory HOME for mysql/mariadb because of missing 
storage in / directory.

Is it not possible to let ProtectHome like it is i.s.o. always reset it 
to true by every upgrade

After each upgrade mariadb cannot be restarted because ProtectHome=true 
and I need to :

Set ProtectHome=false in /etc/systemd/system/mysql.service

systemctl daemon-reload

systemctl start mysql

Thanks for your attention
