Thanks for reporting this; it's a rather serious issue. The problem lies in the 'reinstall-bootloader' procedure. Chiefly, it uses the default bootloader configuration for whatever it can find using 'lookup-bootloader-by-name' and generates menu entries for the generations reachable from '%system-profile', which is quite a bit different from how 'guix system reconfigure' produces the bootloader configuration. It really isn't ideal. To quote a comment in 'system.scm': "[i]t will be enough to allow the system to boot." I don't think this should be _too_ hard to fix. To me, parsing the installed Grub configuration to get existing menu entries seems like a logical step forward. Thoughts from anyone else? Regards, Jakob
