# XXX: Although this looks like all new symbols are enabled when 'make oldconfig' runs, they're not.
#      In fact, you can pipe "yes ''" as well as "yes n", each time leading to the default value being
#      chosen for each unknown symbol.
#      A real solution for that task (disabling everything that's unknown, as we know better) is to
#      upgrade ${TOPDIR}/config so it understands the oldnoconfig target, and using that to update
#      the busybox config before compiling.
#      The workaround for now is to patch all busybox symbols to default n inside the busybox source
#      which do depend on non-existance of other packages outside the busybox source.
