Support for additional DHCP clients is now easy to add.

Just a quick question: are there any plans to use networkd as a DHCP backend? Yes, it is config-file-driven, but one can probably generate the .network files in /run on the fly...

This sounds like pointless masturbation. Just use networkd directly.

That's what I originally thought, and (in a nutshell) this is what I am currently using.

However, networkd config is based on an interface name, not a profile. Hence there are special cases when e.g. 2 wireless networks use different settings (dynamic/static IP, different DNS, etc.). In these scenarios one needs wpa_actiond. As long as the correct profile is selected, one can make use of networkd instead of dhcpcd.

We probably want to improve networkd's [Match] logic, to also work in this case. I.e., to match on SSID. Not on my immediate TODO though, but patches welcome ;-) In general though, I quite like the idea of using networkd as a glorified dhcp client. We probably still lack some features in networkd before to make it support a bit of dynamic configuration before this really makes sense though. Cheers, Tom
