| After hundreds of reboots i can say that these methods when working correctly are 100% predictable from the viewpoint of the remote admin, meaning that every single boot has been successful and no non-reproducable booting errors or failures have occurred yet, barring hardware failures. | After hundreds of reboots i can say that these methods when working correctly are 100% predictable from the viewpoint of the remote admin, meaning that every single boot has been successful and no non-reproducable booting errors or failures have occurred yet, barring hardware failures. | ||

| - | Using other than intel brand nic's can mess with nic interface ordering, especially in debian. If you have nic brands other than intel, and need to boot debian, you must read the important note at the end of the guide in addition to the debian section. You also need a debian installer that includes non-OSS firmware, or you need to include the drivers for your nic in the installer, or you need to add the kernel module manually afterwards (see reference wiki url).// | + | Using other than intel brand nic's can mess with nic interface ordering, especially in debian.

| Set up robinsmidsrod's ipxe scripts at https://gist.github.com/robinsmidsrod/2234639. Ask in #ipxe @ freenode or this thread if you have issues. You need to define the variables and defaults, and have the /boot directory for adding node defaults. Don't worry, that's actually the hard part. Setting up debian and dracut is the easy part :) | Set up robinsmidsrod's ipxe scripts at https://gist.github.com/robinsmidsrod/2234639. Ask in #ipxe @ freenode or this thread if you have issues.
