I like statically IP. How do we know which board would get which IP?
One idea would be to set up a DNS for internal board names. e.g.
panda01.internal.network would resolve to our preallocated static IP
for board "panda01".

This could then be used by the dispatcher to resolve the IP and pass
it to the board through kernel cmdline.

I hadn't really thought of passing it via cmdline. If we need to bring it up statically, we could possibly do that, or possibly just make the necessary adjustments before booting the image. What I was proposing, if the image is already set up to dhcp by default, we could run a dhcp server on the control node with the static ip assignments already in place for each board. That way they always get the same address that we pre-allocated for that board. We'll also need to make sure that the control node has a valid ip on both the internal and the external network.

Thanks,
