Yes, for a long time I cherish idea of "only update /boot/grub and
create core.img" option. May be something like generic

--no-platform-setup

that will simply exit after image is created. --no-nvram is too
specific name to roll this into it. We can then deprecate
--no-bootsector and --no-nvram (actually as --no-bootsector is new just
drop it).

Vladimir, will you agree to a patch?
