Systemd made me stop using Centos 7.
https://jira.mariadb.org/browse/MDEV-10925?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel

In short, the most recent update to Centos7, makes Mariadb unable to start in both versions that use systemd.

This affects millions of users. I had to replace my container for a Fedora 22 one, and lower ,my version of Mariadb.

Does anybody of any work around?
