Extract Config from zImage

It was hard for me to find this simple thing in internet, so I gonna make life for someone a little bit easier.

If you want to extract config file from existing linux image, zImage or bzImage, do the following:

• Download archive file with linux sources.
• Unpack linux kernel sources
• Go into root directory of the kernel sources
• Run chmod 755 ./scripts/extract-ikconfig
• Run ./scripts/extract-ikconfig /tmp/zImage > /tmp/config

Where /tmp/zImage is a file you want to extract a config from. And /tmp/config it is a filename for the extracted config.
