Go into your git checkout folder of ipxe.

Save the below file as nic-menu.ipxe.

Build iPXE like this:

cd src && make EMBED=../nic-menu.ipxe && cd ..

Requirements: current iPXE as of 2013-08-01 (for proper behavior of autoboot with a network device specified, netX feature, PCI vendor/device ID display and inc command)

On the master: puppet cert clean <agent_certname>
On the agent: mv /etc/puppetlabs/puppet/ssl/ /etc/puppetlabs/puppet/ssl_bak

Never do this if you are trying to regenerate the cert for the agent on the master. Instead you would need to delete specific certs

On the agent: puppet agent -t
On the master: puppet cert sign <agent_certname>

	Boot your system into a live CD. Mount your system into the live CD:

	sudo mount /dev/sda1 /mnt
	sudo mount --bind /dev /mnt/dev
	sudo mount --bind /dev/pts /mnt/dev/pts
	sudo mount --bind /proc /mnt/proc
	sudo mount --bind /sys /mnt/sys
	Log into the mounted system:

	sudo chroot /mnt

	#!/bin/bash

	echo "============================"
	echo " pfcrx / pfctx parameters "
	echo "============================"

	for i in /sys/module/mlx?_en ; do
	m=$( basename $i )
	echo "INTERFACE: $m"
	RTX=$( cat $i/parameters/pfcrx )

	#!/bin/bash

	NODES=`sudo puppet cert list --all\|awk '{print $2}'` # Get all node names
	echo '{"facts": [' > facts_tmp.json
	# for node in node: get facts
	echo -n $NODES \| xargs -d " " -i sh -c 'sudo puppet facts find {} --terminus rest \| tr "\n" "," >> facts_tmp.json'
	sed -ie 's/,$//' facts_tmp.json # Remove last comma
	echo ']}' >> facts_tmp.json

	# optionally format and filter json (requires jq)
