   Most importantly, enable the 'gems' source-code repository where the Sculpt
-  scenario resides. In addition, the 'libports', 'ports', 'dde_linux' and
-  'dde_ipxe' repository are needed as well. Second, change the default
-  configuration of the 'QEMU_RUN_OPT' variable to 'image/disk' instead of
-  'image/iso'. This way, the build process will produce a valid disk image
-  with a GPT partition table instead of a legacy ISO image.
