I don't know. I don't think it will have any effect. It is UEFI that refuses to take a new variable. You need to find a way to make it take the variable. The first time it happened, I rebooted and was unable to boot. GRUB did not show up. And selecting the Guix boot option in UEFI boot menu failed to load GRUB. I had to use a Guix installation USB drive to chroot into my installation (section 12 of the guix manual) and fix it. The second and third time it happend, I cleared the dumps via efivars directory the way you did. This allowed me to complete reconfiguring the system each time. It looks like my UEFI behaved better then yours. I do not know whether you can properly roll back the guix system to the last (meaning current) configuration, so that the existing boot option works. Maybe somebody else could comment on this. Roman
