Making a UEFI bootable iPXE USB drive

Build the UEFI executable for iPXE

# First we'll clone iPXE
$ git clone git://git.ipxe.org/ipxe.git
# Go into the src directory of the cloned git repo
$ cd ipxe/src
# Compile the UEFI iPXE executable

Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
}
else {
    filename "undionly.kpxe";
}

	1) Regex matches major identifier — Matches major model identifier numbers based on Apple's knowledge base article (more accurate):

	(^Mac1[34]\|MacBook(10\|9)\|MacBookAir(10\|[7-9])\|Macmini[7-9]\|MacPro[6-7]\|iMacPro1\|iMac(1[6-9]\|2[0-2])),\d\|MacBookPro1(1,[45]\|[2-8],\d)

	2) Regex matches current or higher — Matches model identifiers based on Apple's knowledge base article and may match higher versions before this regex is updated (more future-proof).

	We started by discussing what's new in Yosemite:

	Puppet as a tool is unaffected, due to getting over the issues with Rubby 2.0 in Mavericks.

	The issues with NetInstall and CreateOSXInstallPkg with the distribution pkg format were discussed, as per:
	https://github.com/munki/createOSXinstallPkg#further-note-on-additional-packages-and-yosemite

	SCCM hasn't been well know to immediately support OS releases, nor patch broken functionality in a timely fashion.

	Re: looking to migrate a DeployStudio repo to a new address but reuse nbi's of older version of the OS was given the option of mounting them as they are read/write, and can therefore be updated for new server location. Another point is you can provide auth to automatically run workflows at the NBI level, which is super cool for lab re-imaging.
