dhcpcd-discuss

Hey Roy,

wow, did not expect an answer that fast and with that good content.

I just cloned the repo && built it and I am running dhcpcd now from the
checkout (dhcpcd-8.1.1-36-g81dd5cc5). I'll monitor the behaviour and
give some feedback the next days, if it happened again or whether it's
fixed.

Best,

Nico
