Thanks for the heads-up. Maybe Ondřej might tell us the reason for the
new dependency (it was his pull-request I merged).

I guess users preferring to use ifcfg for interface configuration over
NetworkManager also don't care about rdisc systemd unit.

Is this a theoretical point or to you know of any real use-case where
ifcfg is used? If so, what's the reason for not using nmcli?

So sounds like even more dependencies are required to be formally
correct. Maybe this even justifies putting ifcfg (and probably other
shell scripts as well) into a dedicated sub-package to not impose too
many dependencies onto the core iproute package.

Feel free to submit a patch upstream. Sadly these scripts are not very
well maintained, probably just because hardly anyone uses them.

Not just in Fedora, it seems. ;)
