Just a quick update to say that everything works fine with both dhclient
having the -df parameters pointing to the other lease file.
Deleting both lease files and re-running dhclient result with new lease
files with the same DUID.
All we need now is DHCP clients handling RFC 4361 correctly, I'm
thinking about setting up a dedicated website to raise a little
awareness on this topic because nobody seems in a hurry.
Thanks a lot,
