No. We had been thinking about it but it's unsafe to do that. So instead switch-generation will always reuse the bootloader that was used in the current generation. switch-generation has the same effect as manually selecting another menu entry from the boot menu on bootup would have had - it just additionally defaults to that entry. On the other hand, when you run "guix system reconfigure" or "guix system init": There, it will install and use the (newly) specified one.
