Hello!

I thought I'd brief the readers of this mailing list about the
packaging sprint in London last week. It was organized by Canonical
and in addition to Canonical staff and me there where also people from
Oracle and Percona. We mostly worked on syncing the
MySQL/MariaDB/Percona server packaging and a little bit also on
creating a unified Galera package.

We made good progress and all results have been pushed to public
repos. I also recently updated the pages
https://wiki.debian.org/Teams/MySQL/MariaDB and
https://wiki.debian.org/Teams/MySQL/Galera to reflect the current
status.

One big technical change that was discussed and planned is the
decoupling of the config and data directories. The plan is that in the
future no MySQL variant in particular would anymore own the
/etc/mysql/my.cnf file but instead each variant would register their
own config file at installation time by using the Debian
update-alternatives mechanism. So in future there would be
/etc/mysql/mariadb.conf, mysql.conf, percona.conf etc and some more
snippets in /etc/mysql/mariadb.conf.d/.. etc.

The plan is not complete nor tested, but there are preliminary changes
in the mysql-common package to provide the config file registration
hook and in a preliminary Percona Debian package to use the new config
file registration facility.

As the config file defines the data directory, successful decoupling
of config files would make it easy to also decouple the data
directories so that if the user installs/removes/upgrades any of the
MySQL variants they would not mess up their data accidentally and the
installation scripts would help users to dump/migrate/copy/move their
data in the common scenarios.
