Re: [gentoo-user] Inquiry about gentoo kernel configuration

[Ramon Fischer]

In addition to this:

I did some further research about this, since I actually never thought 
about getting the Kernel sources without having an installed Gentoo system:

You may take a look at one of the HTTP mirrors[1], preferably one in 
your country and navigate to "/releases/<cpu_architecture>/". There you 
will find a Live DVD image - "livedvd-amd64-multilib-20160704.iso" for 
example - from which you could boot from; either virtually in VirtualBox 
or other virtualisation solutions or directly from hardware.

Click on "Login" to login and get the Kernel sources from 
"/usr/src/linux/.config".
