Yep, so we connect OK, start DHCP

But nothing gets received from the DHCP server.  I'm a bit stumped since we 
haven't touched anything related to dhcp between 1.17 and 1.18.  We started 
sending the DHCP rapid commit option in iwd 1.17, so maybe that is why your 
server is ignoring us?

Does starting dhcpcd or something while iwd is in this 'connecting' state obtain 
an IP?

But we're not even getting this far to even invoke resolvconf...

Any chance you can run a git bisect or otherwise narrow down what earlier 
version of iwd was working properly at boot?
