[debian-mysql] Bug#987231: mariadb-server-10.5: Generated /etc/logrotate.d/mariadb has wrong paths

[Matthew Gabeler-Lee]

Package: mariadb-server-10.5
Version: 1:10.5.9-1
Severity: normal

debian/patches/1556.patch contains an update to try to generate a logrotate
config file for mariadb, but it malfunctions almost completely.  The
template used is:

@localstatedir@/mysqld.log @logdir@/mysql.log @localstatedir@/mariadb.log @logdir@/mysql-slow.log @logdir@/mariadb-slow.log @logdir@/error.log

Which results in this:

/var/lib/mysql/mysqld.log /mysql.log /var/lib/mysql/mariadb.log /mysql-slow.log /mariadb-slow.log /error.log

The list of log files, according to commented out defaults in
/etc/mysql/mariadb.conf.d/50-server.cnf, is:

/var/log/mysql/mysql.log /var/log/mysql/mariadb-slow.log /var/log/mysql/error.log

Of course, on a default system, none of these are written any more either,
but they might still exist.  MariaDB definitely isn't going to log to /, and
it seems unlikely for it to log to /var/lib/mysql/.

Why does it matter?  This is causing the logrotate service to fail to start
for me.  It logs what looks like a warning claiming it's skipping the
non-existent files, but then exits.
