I meant, either go into the bios and set the node to netboot, or hit f12(or 
whatever) and netboot. the netbooted discovery image should be able to gather 
all the rest of the bits? Minimal ISO could also be just gpxe or something like 
that and would do the same as above. Then you don't have to update the iso 
every time you enhance discovery process too.

Hmmm... Some bmc's do dhcp though out of the box. I guess if you watched for 
dhcp leases and then tried to contact them over ipmi with a few default 
username/passwords, you'd probably get a fair number of them without much 
effort, if they are preconfigured.

In our experience though, we usually get nodes in that we have to configure 
netboot in the bios, then the next easiest step is to install and then 
configure the bmc via the installed linux. You can manually setup the bmc 
username/password/ip/whatever but its work. Most of the bmc's we've seen have 
ipmi over the network disabled by default. :/ So in that case, the former, 
netboot the box, load a discovery image, and have it configure the bmc all in 
one go would be nicer I think.

Thanks,
Kevin

To boot from minimal iso (which is waht we do now) you still need to tell the 
host to do it. This is where IPMI discovery is needed I guess.
