programmer I know, I thought I toss it around and see what you think.
Many distro's now have pretty good auto-detect features and can detect most
hardware and load the appropriate modules. Yet, most people like to build
their own kernels tuned to their hardware without a lot of extra cruft.
Shouldn't it be possible to boot with a generic kernel, scan the system logs
and create a basic kernel .config file based on the hardware present in the
system? Now I don't expect it to be compete, or even useable directly, but it
could reduce the amount of searching and guessing when you do generate your
kernel .config.
I've read many articles on kernel configuring, but they all suffer from the
fact that there's just too many possible variations to cover everything.
Just a thought.
One could just rely upon hardware detection programs, and then make the
list of modules that are actually loaded after this (with lsmod). Then
map the module names to CONFIG_* parameters. Then merge that with
CONFIG_*=y in /proc/config.gz.
The second task is what's non-trivial. The idea is to search for
statements like "obj-$(CONFIG_AGP_INTEL) += intel-agp.o", so that if
intel.agp.ko is loaded, then you want to define CONFIG_AGP_INTEL=m
(beware of false positives, e.g. for cdrom.ko).
