Option 4 does not work. See response in other email.

5) Disable dhcp at startup? Just like in old isos. This enforce to the
user to know the net-if name at all.

Also remamber that if you boot from PXE, network rename is not posible.
(I guess can be if just after all files copied, shutdown net-if)


@Pierre: I will release archiso-9 on 31 May, with or without any fix for
this issue.
