My test was probably not exhaustive, but added the following two lines
to a init-bottom script did the trick for me:
ip addr flush dev eth0
ip link set dev eth0 down
I tried to boot with kernel parameter ‘ip=192.168.1.200:::::eth0:off’.
Without the init-bottom script the normal network configuration seems
to be ignored (it keeps IP 192.168.1.200 instead), while with the script
eth0 is configured properly (following the /etc/network/interfaces).
I'll see if the linux-initramfs-tool would be willing to accept an
‘unconfigure_networking’ function using ip(1).
