Subject: 2.6.22.7 default kernel configuration

Hi all,

Can please someone let me know what is criteria for default kernel
configuration .

Is it based upon some survey or requested by Fedora or others.

By default configuration size of vmlinux is 41 MB and it includes
approx 75% of useless stuff for me.

what is the idea behind 'default kernel configuration'. Is it made for
developers's PC or for someone else.

Thank you,

Jaswinder Singh.

For i386 it was in the past the .config Linus used for his PC.
There is nu deeper thoughts behind the i386 defconfig.
Other architectures try to let their defconfig cover a lot
because defconfig are often used for test-compiling
stuff (I for once use them a lot).

Other again just chose a popular config and use it for their defconfig.
So no fixed ruleset - and very depending on your architecture.

That's not a i386 or x86-64 defconfig. i386 and x86-64 defconfigs
are ~6.1MB and ~12MB.
