Open SourceArchLinux added Slackware, Fedora and openSUSE distributions in the list have committed migrate from MySQL to MariaDB.

Henceforth MariaDB distributed repositories ArchLinux as the proposed default implementation of MySQL. All require MySQL depends now linked to MariaDB.

To move the current users on MariaDB MySQL requires manual intervention (automated transition was not used because, despite the overall compatibility and the ability to be used as a transparent replacement of MySQL, there are some specific incompatibility).

ArchLinux users recommended not to delay the transition to MariaDB, as packages with MySQL to be removed from the repository in a month. For the migration of the systems installed just install mariadb, libmariadbclient or mariadb-clients and run the script mysql_upgrade:

# Systemctl stop mysqld
# Pacman-S mariadb libmariadbclient mariadb-clients
# Systemctl start mysqld
# Mysql_upgrade-p
