This patch adds support for the Mageia Linux distribution: http://www.mageia.org/ Mageia is a fork of Mandriva although some divergence has already occured and thus inclusion of these changes upstream allow us to (hopefully) migrate more rapidly to the new standard approaches systemd offers. Indeed, we already use the preferred mechanism of OS identification via the /etc/os-release file rather than a distro specific variation. This patch mostly mirrors the patch added previously for Mandriva support. In addition to those original authors, this patch was mostly written by Dexter Morgan with help from Colin Guthrie and Eugeni Dodonov.
