Hi! it seems there's a problem in the /etc/my.cnf config file from this package: log-error= pid-file=/.pid instead of: log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
Thanks for reporting, will fix soon.
Fixed by reverting some changes meant only for rawhide: http://pkgs.fedoraproject.org/cgit/mariadb.git/commit/?h=f21&id=a9d0103564addf23a616cb6051103ecceeb60473
