Ok, this is the issue.  NM expects to receive a response from dhcpcd,
but the dhcpcd that NM spawns is just talking to a master instance which
does not communicate back to NM at all.

If you disable the main system dhcpcd service, I'm betting that will
solve the problem.  It won't prevent NetworkManager from using dhcpcd at
all, because NM spawns a private instance.

systemd mask dhcpcd
