Hi Ludo, I did experiments and I now see that this happens when the boot drive ID has changed from what was specified as the grub-configuration device in the most recent 'system init' or 'system reconfigure' operation. This can happen, for example, when one moves drives around or when one inserts a new drive in an empty lower SATA slot below drives holding GuixSD. This seemed like a bug to me because the doc says ... =E2=80=A2 Make sure the =E2=80=98grub-configuration=E2=80=99 form refers= to the device you want to install GRUB on. ... but there is no mention that it affects boot operation. Also I assumed, possibly wrongly, that GuixSD does not need the config to tell it which device grub is on at boot because it is already running on the boot device ;-) So, I don't know ... Is this a bug or is this expected behavior. If it is not a bug it seems like an opportunity to reduce the fragility of GuixSD configurations. HTH - George
