Yes I know Gentoo is Linux and uses the Linux kernel. My question though is...what differences, if any, exist between the Gentoo kernel you get when you emerge gentoo-sources and the Linux kernel you can download from Kernel.org?

you could also `emerge vanilla-sources` to get the vanilla kernel. :wink:
I can't answer your question though...

Thanks. After your response I realized it was a dumb question. I didn't realize that the Kernel.org kernels are the "vanilla" kernels I kept hearing about. Had I had realized that I could've searched the vanilla kernel vs Gentoo kernel and found my answer.

So...belay my last.

I think it's a good question. http://dev.gentoo.org/~mpagano/genpatches/about.htm Is a start but rather vague. I'd like to know more detail, too.

Vanilla kernel => kernel.org

gentoo sources => vanilla kernel + gentoo pathces => check the contents of the ebuild.

Enabling Gentoo Linux common settings

There is a kernel configuration option called CONFIG_GENTOO_LINUX only present in sys-kernel/gentoo-sources and other Kernel Project maintained kernels. It does nothing on its own, but sets various required configuration options for typical installations.

This setting automatically selects tmpfs and devtmpfs support, which are needed for handling /dev on Gentoo Linux, but might be expanded in the future to enable other mandatory settings for a Gentoo Linux system. For more information, read the help information available through the kernel configuration system as described earlier in this guide.

But gentoo-sources were distinct from vanilla-sources long before that recent configuration item.

I just wondered with Jon Wilder, what the specifics of those changes were. I have also run vanilla-sources and really saw no difference in operation.
