Logrotate not flushing logs in 5.7

[Sander van Schie]

As noted on https://www.percona.com/doc/percona-server/5.7/installation/apt_repo.html the debian-sys-maint user is no longer created by default in Percona Server 5.7. This however results in a logrotate configuration which doesn't flush logs after rotating the log files.

The postrotate script tries to perform a "/usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf ping", which fails as the debian.cnf is no longer present. After this, it checks if mysqld is running and if so does an exit 1:

        postrotate
                test -x /usr/bin/mysqladmin || exit 0

                # If this fails, check debian.conf!
                MYADMIN="/usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf"
                if [ -z "`$MYADMIN ping 2>/dev/null`" ]; then
                  # Really no mysqld or rather a missing debian-sys-maint user?
                  # If this occurs and is not a error please report a bug.
                  if ps cax | grep -q mysqld; then
                    exit 1
                  fi
                else
                  $MYADMIN flush-logs
                fi
        endscript

Is this intended and we are supposed to create the user/file ourselves if we want a working logrotate?
