i see what you mean ... if i start with a .config that contains,
say:
CONFIG_DEFAULT_fred=y
...
CONFIG_PACKAGE_fred=m
then i manually change that second line to:
CONFIG_PACKAGE_fred=n
it will, of course, override the default setting and not be included.
one could get more clever with the hack, but a simpler solution is
just having a make target that builds the image only, so hacks like
this are unnecessary.
