Basically you can just run gbp-clone --pristine-tar git://github.com/ottok/mariadb-X.git to check out the code in all branches and then run git-buildpackage --git-pristine-tar to build directly on your own computer, on with --git-pbuilder to use separate chroot environments for installing build dependencies and building. Without pbuilder you need to manually install the build dependencies with apt-get.
See more commands in script at http://labs.seravo.fi/~otto/mariadb-repo/build.sh

How MariaDB works
Simply writing apt-get install mariadb-server will install MariaDB 5.5.x and replace any existing MySQL 5.5.x installation and inherit the databases and configuration files of it. Installing mysql-server will do the opposite. However running mysql-server might raise issues if my.cnf contains something MariaDB-specific or if the database files have some MariaDB-specific table metadata. In those cases MySQL should fail gracefully by simply refusing to start until conditions are correct.
Most MariaDB packages have in the control files Provides+Breaks+Replaces for equivalent MySQL packages, so that it is impossible to install both at the same time. Many of the packages contain the same (and thus conflicting) file names and paths as in equivalent MySQL packages.
- Upstream MariaDB 5.5.x advertises to be a binary-compatible replacement for MySQL 5.5.x (but not anymore for MySQL 5.6 vs. MariaDB 10.0). Anything that works with MySQL 5.5 will work with MariaDB 5.5. Migrating from MySQL 5.5 to MariaDB 5.5 will always work. The contrary might not always be true, as at least MariaDB 5.5 libraries (/usr/lib/x86_64-linux-gnu/libmariadbclient.so.18.0.0) have more symbols (e.g. async support) than the MySQL version and some MariaDB enhanced database tables may be unreadable by MySQL 5.5.
Possible "interfaces" of MySQL 5.5 are the server and client binaries (can be used e.g. in shell scripts), the actual server interface (used remotely via port 3306 or locally via socket /var/run/mysqld/mysqld.sock) and the binary interfaces (/usr/lib/x86_64-linux-gnu/libmysqlclient.so.18 and some symbolic links to it, installable from package libmysqlclient18). MariaDB has all of these interfaces, plus the extra libmariadbclient18.so.18.
As upstream MariaDB 5.5 is quite an young fork of MySQL, all of the internal file names still have mysql in them, the database files are in the same location, the configuration file /etc/mysql/my.cnf is the same, the port 3306 is the same etc.
In Debian packages, libmysqlclient.so.* has been renamed to libmariadbclient.so.* to enable both versions to be installable side-by-side. Initial checking did not find that MySQL nor MariaDB would themselves use the shared libs, but have their own libs statically linked in. These shared libs are meant only for third party usage, and the libs themselves will use whatever server is installed (MySQL or MariaDB). While libmysqlclient18 and libmariadbclient18 are co-installable, the -dev versions have files with same filenames and they conflict, thus making -dev versions NOT co-installable.
Mariadb-common is an empty metapackage that depends on mysql-common. MariaDB 5.5 can always use a my.cnf that originates from MySQL 5.5, but it might not work the other way around if the user has added some MariaDB-specific parameters in the my.cnf. The default my.cnf should always be compatible with all MySQL and MariaDB versions (5.5, 5.6, 10.0 and foreseeable future). Any options which are unique to one or the other must never appear in a shipped my.cnf.
- To mitigate migration confusion, installing MariaDB will show an dialog notifying about the potential one-wayness of the migration.
- As MariaDB stores data in /var/lib/mysql, there might be issues if somebody wants to run MySQL after using MariaDB for some time. We could ask upstream to copy /var/lib/mysql into /var/lib/mariadb to be on the safe side. In Debian installing MySQL after MariaDB could also be seen as a downgrade, and trigger the mariadb-server-5.5.preinst:77 downgrade warning. The current solution is simply to issue a warning at MariaDB installation time that the migration for some parts in a one-way migration.

Notes related to licensing
In the future it might be possible to run something like
licensecheck --copyright -r . -c . | /usr/lib/cdbs/licensecheck2dep5 > /tmp/copyright
..but at the moment it does not work, so the license file is a hybrid with automation plus manual clean up.
Script license-reconcile can be used to lint the copyright file, but it cannot generate a correct file.
Related issue filed upstream: https://mariadb.atlassian.net/browse/MDEV-5483
SONAME is defined inside the shared library and to change if the build source itself must be updated. Filed issue https://mariadb.atlassian.net/browse/MDEV-5482)
- Should libmariadbclient18 depend on package libmysqlclient18? Can that work it the -dev versions of the same packages conflict?
- Should libmariadbclient18 be ditched altoghether because nobody anyway links their programs to the libmariadbclient18.so shared library? Should the LGPL MariaDB client library be adopted here instead? Is is feature complete enough?
- In which package should the file libmysqld.so live? Should that package depend also on mariadb-server and draw in all of server because the shared lib uses stuff from the server package?
Review debian/patches, do we really need them? At least remove the temporary mysqld_safe-extrafix which was added only to satisfy dpkg-source nag.
Figure out optimal way to add Ubuntu patches upon the Debian base and after that file issue upstream to get rid of debian/dists/(Debian|Ubuntu) folder.
Figure out and document the optimal workflow to from importing upstream changes (using git-dch with correct parameters etc), committing, testing and all the way to uploading into Debian.
Discuss with upstream to bump up the Debian policy version, rename *.files into *.install etc.
Talk with upstream about autobake.sh and possible removal or simplification to run same build process as Debian does.
Ask upstream to have one autobake run for our git also, so that we can benefit from the continuous integration system there https://mariadb.com/kb/en/package-testing-with-buildbot-and-kvm/)-- See now http://buildbot.askmonty.org/buildbot/builders/debpkg-trusty and http://buildbot.askmonty.org/buildbot/builders/debpkg-sid
--(In general, minimize delta with upstream to make maintenance and updates easier See README.Maintainer, updating is now very easy.
Ask upstream to GPG sign their tar.gz packages. Then we could use the new uscan feature: As of devscripts 2.13.3, uscan now supports verifying cryptographic signatures on upstream source via the pgpsigurlmangle option in debian/watch. See uscan(1) for details and examples. (or https://wiki.debian.org/debian/watch/#Cryptographic_signature_verification))--
Add ci.debian.net integration like MySQL has: http://ci.debian.net/#package/mysql-5.5
- Rename libmariadbclient-dev to libmariadbclient18-dev
- Use utf-8 as default in my.cnf as Gentoo does and most users probably want (instead of current latin-1)?
- Move data in 10.0 to /var/lib/mariadb
- Add question to installer to make feedback plugin opt-in very easy.
