Multiple bootloaders share a name (including both versions of extlinux) and bootloader-configuration data is significant to bootloader installation. It shouldn't be just faked. Rely on the provenance service instead, which while not always present, should be for the vast majority of systems. * guix/scripts/system.scm (reinstall-bootloader): Rename to... (install-bootloader-from-provenance): ...this, and rewrite to extract bootloader-configuration data from system provenance. (switch-to-system-generation, process-command): Use install-bootloader-from-provenance.
