I noticed an obvious issue in (gnu build linux-boot), which is that device-mapping (the #:pre-mount argument) would be performed after ‘mount-root-file-system’ has been called.
Commit 67979e4 fixes that. To fix it, we’ll have to update ‘guix-devel’ in (gnu packages package-management), and to regenerate a VM image that uses it. I can help with that. Ludo’.
