Just wondering if anyone has any experience setting up a net boot server that can be used to kickstart EFI machines?
Yep.
In ISC dhcpd.conf, use:
next-server config.example.com;
if option architecture-type = 00:07 {
filename "shim.efi";
} else {
filename "pxelinux.0";
}
Then, in your tftp server you'll need 3 files from the shim and
grub2-efi packages. I used this script:
---
#!/bin/sh
wget
http://centos.s.uw.edu/centos/7/os/x86_64/Packages/shim-0.7-5.2.el7.centos.2.x86_64.rpm
wget
http://centos.s.uw.edu/centos/7/os/x86_64/Packages/grub2-efi-2.02-0.16.el7.centos.x86_64.rpm
mkdir tmp
rpm2cpio shim-0.7-5.2.el7.centos.2.x86_64.rpm | (cd tmp && cpio -ivd)
rpm2cpio grub2-efi-2.02-0.16.el7.centos.x86_64.rpm | (cd tmp && cpio -ivd)
cp tmp/boot/efi/EFI/centos/shim.efi ../
cp tmp/boot/efi/EFI/centos/grubx64.efi ../
cp tmp/boot/efi/EFI/centos/fonts/unicode.pf2 ../grub/fonts/
rm tmp -rf

Configuration files are in EFI/centos (relative to the TFTP root) rather
than pxelinux.cfg. They're named grub.cfg-01-<mac>, and use grub syntax
rather than isolinux syntax.
A simple example:
---
set timeout=600
set default=0
menuentry "localboot" {
insmod chain
set root=(hd0)
chainloader +1
}
menuentry "c7" {
linuxefi /c7/vmlinuz ks=http://config.example.com/kickstart/c7s
ksdevice=eth0 net.ifnames=0 biosdevname=0
initrdefi /c7/initrd.img
}
