[debian-mysql] Bug#996706: mariadb-server-10.5: run directory is not created in multi-instance mode

[Peter Keresztes Schmidt]

Package: mariadb-server-10.5
Version: 1:10.5.12-0+deb11u1
Severity: normal
X-Debbugs-Cc: carbenium at outlook.com

Dear Maintainer,

Starting mariadb as multi-instance service (mariadb at instance-name.service) fails
since the run directory (/run/mysqld) is not created.

The normal unit file (mariadb.service) contains following line:
  ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/run/mysqld

This is missing from mariadb at .service. In buster both unit files contain the line.

Upstream I saw that tmpfiles config generation is implementend
since 7bbc6c14d1e8fcf1f4737e0a5fcf6237fe18bd23, but I don't see those files shipped with the package.

Thanks for looking into this!

Regards,
Peter
