Subject: [sisuite-users] proposed patch: parse $DEVICE to dhclient in
start_network

It seems the sisuite-devel list is members only and it won't subscribe
me, so I'll post this here then.
Installing a new cluster at SARA, I came across the following issue with
systemimager 3.8.0.
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).
Kind regards,
- Ramon.
