Hi!

This debbugs thread got already very long. Therefore I would like to focus on the grub changes in this ticket done with my last patch, see <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=41011#95>

This patch only introduces a new grub-net bootloader, which basically installs grub via its grub-mknetdir command.

There is no modification of other bootloaders. The restriction of the “/boot/grub/grub.cfg” file remains.

As usually the DHCP option 67 “Bootfile name” is involved to point the EFI of a machine to the file to boot via TFTP, I chose to export (install-grub-net subdir) as well to be able to modify that path, whose default is /boot/efi/Guix/boot[x64|aa64|…].efi, to something else, e.g.

(bootloader (inherit grub-net-bootloader (installer (install-grub-net "efi/machine-1"))))

To be able to boot different machines with their own guix installation, however, there is still the problem to provide to each an own grub.cfg file via TFTP. This file – as you know – has still a hard coded path of /boot/grub/grub.cfg. But this is a different issue and should not be tackled with this patch.


Bye

Stefan
