binary kernel package == source package ?

narc · 07-29-2007, 12:32 AM

I wanted to compile a kernel from the source package to change a few options.

Is the .config file in Ubuntu 7.04's kernel source package the same as the default .config used by the maintainers when they create the binary distribution ?

I've compiled kernels before but it happened to me that the distro's acting kernel was way different than what is selected in the .config file of the source package. The distro's kernel recognizes many of my devices and lsmod tells me my machine has 105 modules loaded. I don't want to start everything from scratch and check if every option in the .config file is identical to the current state of my box.

Any insight on subject ?

Many thanks.

Your /boot directory should contain config files with the options used for each of the kernels in /boot.

Actually, no.

Holy sh*t.

:-)

I was, evidently, looking for a .config file.

Thanks a lot.
