The root filesystem is on NFS.

Yes they're all available, the dhcp server would not offer them if not. I *think* this is done by the kernel: It will decline all attempts to set an IP-Address different from the one where the root-filesystem is mounted because that would kill the system. Note that the very-first IP-Address offered above is the one the system already has, in fact it is configured as a static IP for this MAC address in the DHCP server. It should accept that even though the interface is already up with that IP. So the error "RTNETLINK answers: File exists" is probably the cause of all this. It did not occur on earlier Debian version such as Buster (or it did occur and was ignored by dhclient?). It has worked for me as far back as Debian lenny. I'll try to boot the system with debian buster but with the same new kernel and report back.
