Hmm, what’s that IPv6 address?  Is it here even if you do not configure
any IPv6 address in ‘static-networking’?

Julien, could the ‘link-set’ call in ‘network-set-up/linux’ be the
culprit?

    #$@(map (lambda (address)
              #~(begin
                  (addr-add #$(network-address-device address)
                            #$(network-address-value address)
                            #:ipv6?
                            #$(network-address-ipv6? address))
                  ;; FIXME: loopback?
                  (link-set #$(network-address-device address)
                            #:up #t)))
            addresses)

It seems to be the only way to mark the device as “up”, but since it has
arguments that seem redundant with those of ‘addr-add’, I wonder if
something could go wrong here.

Thanks for testing, Vivien!

Ludo’.
