bug#27231: regression?: grub-configuration for grub-efi does not return a bootloader-configuration

[pelzflorian (Florian Pelz)]

Hello,

My GuixSD configuration (see attachment) for UEFI got broken some
three weeks ago but I’ve only now caught up with my e-mail and “fixed”
it.

address@hidden ~# guix system reconfigure /home/florian/keep/guixsd-asus.scm

I ‘guix pull’ed before reconfiguring.

I used this:

  (bootloader (grub-configuration (device "/dev/sda")
                                  (grub grub-efi)))

Then ‘guix system reconfigure /home/florian/keep/guixsd-asus.scm’ kept
failing. Debugging by (load)ing .guix-real in the Guile REPL and using
breakpoints showed me that this was not a valid
(bootloader-configuration?).

Replacing the above by

  (bootloader (bootloader-configuration (bootloader grub-efi-bootloader)
                                        (device "/dev/sda")))

fixed it today and I can ‘guix system reconfigure’ again.

I don’t know why this broke and if it breaks for others too
(apparently noone has filed a bug yet), which is why I’m filing a bug
here. Using a syntax rule for grub-configuration seems complicated to
me anyway, but I’m still a Guile newbie.

Florian
