Hi Guix: I have this nice GNU hacker background that ages ago some system installed as the GRUB background then. I'd like to use it as GRUB background in Guix System now.
I tried to set it thus, along the lines of GRUB theming instruction in the manual: (grub-configuration (theme (grub-theme (inherit %default-theme) (background_image '("/home/shiroikuma/0/pictures/grub/gnu-grub.jpg"))))) But it doesn't work — gives me an invalid field specifier — so I guess “background_image” cannot be specified this way. Any other way to do it? -- Best regards / 宜しく御願い致します / S pozdravem / C уважением / Z poważaniem / Mit freundlichen Grüßen 白い熊
