I got this working in the end.
A few key takeaways if anyone else is looking at this.
If you are using debian for the nfsroot, you have to use buster, as Secure
Boot was not supported properly on any release before that.
The nfsroot should contain these packages: shim-signed,
grub-efi-amd64-signed
You have to use grub as the boot loader, not syslinux.
Make sure the following files are copied into your tftp dir:
NFSROOT/usr/lib/shim/shimx64.efi.signed -> bootx64.efi
NFSROOT/usr/lib/grub/x86_64-efi-signed/grubnetx64.efi.signed -> grubx64.efi
NFSROOT/usr/share/grub/unicode.pf2 -> grub/fonts/unicode.pf2
NFSROOT/usr/lib/grub/x86_64-efi -> grub/x86_64-efi
You may also need to symlink the grub dir back from the tftp root, in our
case that looked like: TFTP_DIR/grub -> TFTP_DIR/fai/grub
Then you need a grub.cfg in: TFTP_DIR/fai/grub/grub.cfg
Ours looked a little like this:
set default="0"
set timeout=1
if loadfont unicode ; then
set gfxmode=auto
set locale_dir=$prefix/locale
set lang=en_US
fi
terminal_output gfxterm
set menu_color_normal=white/black
set menu_color_highlight=black/light-gray
if background_color 44,0,30; then
clear
fi
menuentry 'FAI' {
linux fai/vmlinuz console=ttyS0,115200n8 console=tty0 ip=dhcp
root=1.2.3.4:/srv/fai/nfsroot/filesystem.dir rootovl
FAI_FLAGS=verbose,sshd,createvt,reboot FAI_ACTION=install
rd.net.timeout.carrier=20 rd.net.timeout.ifup=30 BOOTIF=$net_default_mac
initrd fai/initrd.img
}
Cheers,
Just
