Lack of config defaults in 10.1.13

Install MariaDB Server 10.1.13 from the CentOS 7 repository.

Look at /etc/my.cnf, which basically tells you:
!includedir /etc/my.cnf.d

Now look at server.cnf - everything is commented out

The only useful config file is enable_encryption.preset

Contrast this with an install of MySQL 5.6 even... I know the useful files are now in /usr/share/mysql (e.g. my-huge.cnf, my-small.cnf, etc.) but there must be some kind of sensible out of the box default for people to use
