I believe it will work, but booting older GRUB entries in Guix comes with a distinct inconvenience. To my knowledge, it is difficult to tell in which iteration you are once you have booted. Ideally, you would merely "roll back" to the system iteration you identified as stable. Then the generation that 'guix system list-generations' shows as (current) corresponds to the system you are in, and grub.cfg will be rewritten to put that iteration on top. In that workflow, there is no need to touch the default. Personally, I think it's easier to maintain (and update) but please feel free to experiment to find out what works best for you. Kind regards Felix
