+# NOTE: This is currently horrifically broken. See the ongoing drama around
+# systemd-networkd on cent8. Basically triggering an update- or an install- will give
+# a conflict error due to the spicy-jankaroni-with-extra-cheese edition of
+# systemd-networkd I'm running. We can exclude "systemd*", but we need to install
+# systemd-devel so then we get a package not found error. Its a truly stupid problem
+# that will hopefully all go away when this bug gets fixed and systemd-networkd becomes
+# available in EPEL:
