Description of problem: Add a note to /etc/fedora-release marking it as deprecated. I would suggest adding a note as follows: # Starting with Fedora 21, /etc/fedora-release file is deprecated. It should not # be used to identify a Fedora system. This file will be removed in a future # release. Instead /etc/os-release is the canonical cross distribution # default file to identify a distribution. It should be read first with a # fallback to /usr/lib/os-release. Refer to the man page of os-release (man # os-release) for details. Reference: https://www.suse.com/releasenotes/x86_64/SUSE-SLED/12/#Packages.Deprecated
It is not deprecated.
