To Reproduce
Steps to reproduce the behavior:

1. add macvlan

macvlans = {
  macvlan1 = { interface = "enp4s0"; mode = "bridge"; };
};

2. rebuild
3. see ip a

Expected behavior

rebuild should activate new services like macvlan1-netdev.service

This is most likely some dependency problem in the scripted networking framework.

Maybe using the networkd backend as a workaround might help?
