I'm sorry, Tobias, I was mistaken — I thought it had to go in the “(grub-configuration” section under “(bootloader”. Thanks for posting your config — I saw the mistake.

Anyhow, now “system reconfigure” still won't finish.

With the bootloader section like:

(bootloader (bootloader-configuration
(bootloader grub-bootloader)
(target "/dev/sda")))

… it reconfigures fine.

If I change to:

(bootloader (bootloader-configuration
(bootloader grub-bootloader)
(target "/dev/sda")
(theme (grub-theme
(inherit %default-theme)
(images (list (grub-image
(aspect-ratio 4/3) ; or 16/9, &c., to match…
(file (local-file "/home/shiroikuma/0/pictures/grub/gnu-grub.jpg")))))))))

… the reconfigure fails with:

Thanks for helping. :@)
