but the default build isn't base on my configuration (i enable 'Handle and
preserve segments').
if i don't set BUILDDIR to l4_all/kernel/fiasco/build. how does default
build know
how i config fiasco?

last time, you mentioned that :
"Yes, a default configuration is built into kernel/fiasco/build upon make
in the l4 directory if not configured otherwise (see the L4
configuration menu)."
but i can't find any option in L4 configuration menu which is about fiasco?

thanks for answering.
