How works Genkernel's non-interactive 'make oldconfig'

Hi,
I don't know if this the right mailing list, but I give it a
try.

I'm writing a software to manage the upgrading, rebuild,
uninstallation of the 
linux kernel.

Now, what I need is a non-interactive 'make oldconfig' like
genkernel does it. 
I looked at the code, but couldn't find the right line. Can
anyone tell me at 
which files and lines I have to look for this feature.
Thanks.

regards
 Arne

No, 'make silentoldconfig' just suppresses the already
answered (by the old 
config) options. It still prompt for new options.

Thanks.

try:
echo y | make oldconfig

That's not really safe.  You want to use the defaults, which
is what I
think 'silentoldconfig' does.  You really don't want to
enable an option
like "Add self-destruct mode" to the kernel if it
is newly present

Great. Works like a charm.
Thanks.

Good point. I will then use "echo n | make
oldconfig" by default.

Where's the fun in that!!

I'm not sure that really removes the danger.  What if they
split out a
driver you need into some other config option?  If there's a
way to
echo a newline to all the questions, that would at least
accept the
defaults.

Pardon me for being reactionary, but does
"non-interactive kernel
configuration" give anyone else the cold sweats?

Are you sure you want that too?  What if there's the new
"Make
your box run twice as fast" option?  You need to pick
the default option
value, which I'm pretty sure that 'silentoldconfig' does.

So please use that one to get things "correct".

thanks,
