No part of it makes sense on Guix (except=20 =E2=80=98quiet=E2=80=99, which is handled by the kernel itself, and see bel= ow for=20 that). GRUB_CMDLINE_LINUX_DEFAULT (and similar-looking variables) is used=20 only by the =E2=80=98update-grub=E2=80=99 utility on some distributions tha= t uses=20 a bash configuration file to configure a bash script that creates=20 the final (bash-like) grub.cfg. As it sounds, it's a pretty horrible system, and it's not used by=20 Guix at all. grub.cfg is generated entirely by Guix itself, based=20 on your operating-system record and previous system generations. Adding =E2=80=98splash=E2=80=99 is equally specific to some other distribut= ion,=20 and has no effect on Guix System. There is no splash screen code in Guix. Plymouth has been=20 packaged, but there's no code to launch it at boot. I haven't=20 even managed to make a =E2=80=98flicker-free boot=E2=80=99 happen on my i91= 5. > the problem is that based on current bootloader definition,=20 > there is no > option exposed for additional grub configurations (or I might=20 > missed > the proper option for this). (operating-system ... (kernel-arguments '("quiet"))) This will hide many but not all messages. A silent boot, with or=20 without a splash screen, is currently not a feature of Guix.
