Found in /tmp/upgrade.log after upgrade of RH 7.0+some updates to fairfax beta1: Upgrading dhcpcd. mv: `/etc/dhcpcd/dhcpc' and `/etc/dhcpc/dhcpc' are the same file erase unlink of /etc/dhcpcd/dhcpc failed: no such file or directory. I didn't think to check version pre-upgrade. After upgrade it was dhcpcd-1.3.18p8-11
This defect considered SHOULD-FIX for Fairfax gold-release.
It appears that Nalin fixed this a long time ago
