That's it.

Well, by default the bootloader is assumed to be grub (because grub is
the only supported bootloader in pre-rework guix).
For the boot-device, it is set to #f if not read in parameter
file. During a switch-genereation if boot-device is #f, the
configuration is updated, but the bootloader is not reinstalled.
It was already what happended before my rework. The bootloader was not
reinstalled because we cannot be certain to reinstall the same grub
version as the one installed.
