.config question

.config question

[Francois Pernet]

Hi,
Sorry to not be part of the mailing list and ask question. Please,
could you post any answer (CC) to this question, if relevant ? Many
TIA.

I've got a kernel already installed in my machine (SuSe Pro 9). I would
like to modify something and recompile the kernel. Since it has been
installed from rpm, there is no .config in /usr/src/linux. Is there any
way to create this file from the image and modules, so i do not need to
verify all my config prior to change something ?

Thx

Make sure you have the kernel source package installed. Then read
/usr/src/linux/README.SuSE, especially "How to configure the kernel
sources" and "Where to find configuration files"

maybe /boot/config-`uname -r` ?

Suse Pro 9.1 has a copy of the running kernelconfig in /proc/config.gz.
Type 'zcat /proc/config.gz > /usr/src/linux/.confg' to copy it to your 
sourcetree.

Probably show up on the list, otherwise likely to be a silent fix RSN.
I was surprised that it hadn't been posted, spent time making sure
that I could repeat it....but it could still be something in my setup.

There is an option in 2.6 to determine the .config that built the
kernel somehow.  I've just noticed it while reading 'make xconfig',
but never use it (I don't lose track of my .config files, been doing
that tooo long).  Try reading the source for how this is supposed to
work.  You might look around a bit, such as in /boot, as many distros
include the config someplace.
