Feature #12635
Updated by Lukas Zapletal about 8 years ago
It looks like Grub2 is the best and most compatible way of PXE booting EFI hardware and it is available in most Linux distributions. It makes sense to provide support in our Puppet classes and installer to deploy these. Puppet changes as follows: if RHEL6 or Fedora 18 or older is found then install grub package create /var/lib/tftproot/grub/ copy /boot/efi/EFI/*/grub.efi Instructions on where to /var/lib/tftproot/grub/grubx64.efi create a *relative* symlink shim.efi to /var/lib/tftproot/grub/grubx64.efi ensure correct file permissions and SELinux context if find the firmware in RHEL7 are at https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Installation_Guide/chap-installation-server-setup.html (RHEL6 does not ship Grub2 so installer should fail or Fedora 19 or newer is found then install packages: grub2-efi grub2-efi-modules grub2-tools create /var/lib/tftproot/grub2/ copy /boot/efi/EFI/*/grubx64.efi to /var/lib/tftproot/grub2/grubx64s.efi copy /boot/efi/EFI/*/shim.efi to /var/lib/tftproot/grub2/shim.efi build grub2 with all modules with: grub2-mkimage -O x86_64-efi -d /usr/lib/grub/x86_64-efi -o /var/lib/tftproot/grub2/grubx64.efi -p "" `find /usr/lib/grub/x86_64-efi/*.mod -printf "%f " | sed -e 's/\.mod//g'` (X) ensure correct file permissions skip that). Similarly for Debian and SELinux context if Debian or Ubuntu it is found then install packages: grub-common grub-efi-amd64-bin create /var/lib/tftproot/grub2/ build grub2 with all modules with: grub-mkimage -O x86_64-efi -d /usr/lib/grub/x86_64-efi -o /var/lib/tftproot/grub2/grubx64.efi -p "" `find /usr/lib/grub/x86_64-efi/*.mod -printf "%f " | sed -e 's/\.mod//g'` (X) create a *relative* symlink shim.efi to /var/lib/tftproot/grub/grubx64.efi ensure correct file permissions I have only tested this with latest LTS Ubuntu and Debian Jessie (8) (X) - this command could be extracted to a helper script available for direct download at http://archive.ubuntu.com/ubuntu/dists/trusty/main/uefi/grub2-amd64/current/ or in debian-installer-8-netboot-amd64 package.
