Hi,

Karl Hallsby <karl <at> hallsby.com> skribis:

> For single-disk installs (external USBs) and for amnesiac UEFIs, Guix is not
> found using its default Grub EFI bootloader location of
> /boot/efi/EFI/Guix/grubx64.efi means the Guix install will not be found.
>
> To handle this, we can place the bootloader file in the UEFI specification
> location, overwriting any other OS that may have placed a file there. This
> location is namely /boot/efi/EFI/BOOT/BOOTX64.efi. Grub has explicit support
> for this location/situation with the `--removable` flag.

Interesting.  The patch LGTM; one last thing: could you add a couple of
lines in doc/guix.texi, under “Bootloader Configuration” (next to where
‘grub-efi-netboot-bootloader’ is described) describing
‘grub-efi-removable-bootloader’?

With that in place, we should be all set.

Thanks in advance,
Ludo’.
