I'm working on getting some PXE stuff going with about 40 clusters. I'd like to have all of the IPs uniform.

When the PXE agent starts, it uses the MAC address that the motherboard should have and as such gets an ip associated with it like 192.168.66.150.

Once Debian gets going though, it reads a different MAC address(because of a hardware or something, either way, this is what I need to work around) off of the motherboard and gets a different IP like 192.168.66.149.

I'd like to keep it as one uniform IP throughout the entire booting procedure so I don't have IPs that effectively only existed for the sake of PXE booting and such.

Please, anyone have any ideas?
I've tried setting the hwaddress in /etc/network/interfaces but that's too late in the game. I need to change the physical address before it tries to mount the NFS root partition(which is when the computer acquires 192.168.66.149)


Please help! Thanks!
