Regarding the discussion about adding cases to --no-bootloader, I think this belongs into the configuration, not an option given to `guix system reconfigure`, which one might forget to pass all too easily. -- Thorsten Wilms thorwil's design for free software: http://thorwil.wordpress.com/

Dual-booting solution with only one actual Grub installation
Hi once again,
There's a convenient dual-booting solution that I think hasn't been
mentioned in these circles. You can let Grub2 offer an item that will
load another grub.cfg.
In my case, that's a Grub installed from Ubuntu, with a menu that will
be updated in sync with kernel installation/removal, plus one "Guix SD"
item that will lead to the known Guix SD menu, also always up-to-date,
without an actual second Grub installation.
No manual updating, no chain-loading of one or the other from an
independent third Grub.
Guix SD: /etc/config.scm, in operating-system:
(bootloader (bootloader-configuration (bootloader (bootloader (inherit
grub-bootloader) (installer #~(const #t))
Thanks to snape in #guix. With this, /boot/grub/grub.cfg will be
generated, but Grub won't actually be installed.
Other system with Grub in MBR, addition to: /etc/grub.d/40_custom:
menuentry 'GuixSD' {
search --fs-uuid --set=root a3a97a6f-a4c9-4569-98a3-4306f4db9ff8
configfile /boot/grub/grub.cfg
}
Don't forget `sudo update-grub`.
