Thanks guys for looking into this. I finally got my containers working again today so I could reproduce. There was a bug in sd-dhcp-server so that it would never send out broadcast packets (so the change defaulting to requesting broadcast in the client obviously broke everything). I fixed that now in git, so let me know if there are any more problems.
