We have multiple network interfaces, which are all configured through DHCP. Now a problem arises when the SystemImager initrd does a "start_network", which is that dhclient is called for _all_ ethernet interfaces.
This causes in turn a race condition: whichever network responds first to the dhcp requests, is used to (try to) install the node. This is turn doesn't work when the network with incorrect dhcp settings wins.
However according to the wiki page the kernel/environment argument DEVICE=<something> should be used to contact the imageserver.
This can be fixed/prevented easily by using $DEVICE as cmdline argument to dhclient in the initrd functions, attached my patch for this. That way only $DEVICE gets configured through dhcp (during installation).
