I work at a company that likes to poweroff our entire buildings on a yearly bassis. During the powerup we tend to have a chicken-and-egg problem. All our servers are set to PXE boot on every boot. Some of the core infrastructure servers end up getting stuck on boot. A DHCP server is a available to respond, but no tftpserver is up yet to send down the pxelinux microkernel. Is there anyway to have multiple tftpservers specified? Any other suggestions outside of getting our tftpserver up first.
