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).

No, it's a default build.

No. The way you build the kernel is fine.
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.

With this statement I'm trying to express that for L4Linux one should
_not_ enable any option that is close to the hardware, such as ACPI,
HPET, MTRR etc. Remember, L4Linux is a normal user program and as such
has no business doing anything with timer hardware or interrupt
controller or similar. On the other side, you can enable e.g. any
filesystem you like.
