I suppose there is no chance to find out which interface had been used for the
actual PXE booting?
For IPMI reasons, eth0 of multi-homed machines may be a public interface
and eth1 the "private" one which is connected to the installation network.
In such a case, the first DHCP response might be returned from the public
network even if PXE booting took place on eth1. (which has preference in
the BIOS boot order, btw)
I still don't understand why we can't have back ip=::::::eth1
