Fedora+systemd changed deprecated /etc/sysconfig/network which was used by IPA to store static hostname for the IPA machine. See https://bugzilla.redhat.com/show_bug.cgi?id=881785 for details. Change Fedora platform files to store the hostname to /etc/hostname instead. https://fedorahosted.org/freeipa/ticket/3279
