-The PBXT/PrimeBase engine is unsupported upstream in MySQL & MariaDB for some
-time now [1]. It is no longer built in the upstream MariaDB 5.5 binaries[2][3]
-and if it is enabled in a source build, it fails many tests [4].
-
-In light of this, the MySQL team has decided to mask it in
-profiles/base/package.use.mask for all relevant packages.

-
-All users who have data stored in PBXT-backed tables MUST convert the tables
-to another format BEFORE upgrading to MySQL/MariaDB 5.5, as the tables will
-become inaccessible otherwise.
-
-We will continue to allow it to be built in the 5.0/5.1 series, to make the
-above data migration easy, but we strongly encourage all users to move their
-data out of the PBXT engine.
-
-If you need to check for PBXT tables easily, look in your MySQL/MariaDB
-datadir for any files with a .xt extension.
