Thank you for your PR at https://github.com/ottok/mariadb-10.0/pull/25
I will merge it and after that it will automatically be available in Debian unstable and eventually in new releases of Debian and Ubuntu. Due to Debian and Ubuntu policies it is difficult to backport these kind of changes and get bugfixes into stable releases. Note: In the postinstall file there is a line ```mysql_upgradedir=/var/lib/mysql-upgrade``` defined but it is not used anywhere. I wonder if the original feature is used at all. The MariaDB packaging is inherited from https://anonscm.debian.org/cgit/pkg-mysql/mysql-5.6.git/tree/debian/mysql-server-5.6.preinst?id=refs/heads/master#n140 and non-use of it from https://anonscm.debian.org/cgit/pkg-mysql/mysql-5.6.git/tree/debian/mysql-server-5.6.postinst?id=refs/heads/master I don't see any particular spot where the mysql-upgrade directory is used, thus I don't know where it would be safe to clean it up. Anyway the line in question works if the symbolic link to the mysql datadir is relative and fails it if is absolute. Your '-T' fixes the cases where the datadir link is absolute and dpkg will at least not fail on upgrades in those cases in the future. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
