https://github.com/NetworkConfiguration/dhcpcd/tree/hurd_test
The port itself is feature complete, Joan also has some improvements in a separate branch but I have yet to look at that.

The people in #hurd have been very helpful with suggestions.

My main concern is that AFAIK my local changes to headers *might* have been fixed in Debian but they have not been fixed in Gentoo.
Even with these changes there is too much header churn: https://sourceware.org/bugzilla/show_bug.cgi?id=11142
Debian does not provide a Hurd image I can use.
Gentoo does not provide a Hurd image I can upgrade.

Until the above changes I'm not going to spend more time on this project beyond keeping the hurd_test branch.

Thanks 

Roy
