Hi, here a feature request.

The idea basically is can use a little file with the configuration we want for the kernel.

When we config the kernel normaly we don't change all the options, only the options we need and use the other in the default value, but with the upgrades we most start selecting again all the options, so can use a little file with the options we want and obviously it need check the features and the deprecated features for can update the options.

Thx.

Good idea, I like it.

I don't understand that feature request.

Put all your options you want in /root/my-kernel-options.conf. Now call genkernel with "--kernel-config=/root/my-kernel-options.conf". It will start building kernel with your provided "snippet" and thanks to "make oldconfig" magic, missing (but available) options will be added.

The problem are features which are normally not enabled and have other requirements: I.e. an option currently not even present as "not set" in config because it's unavailable due to missing requirements, can't be enabled that way.

When I implemented https://gitweb.gentoo.org/proj/genkernel.git/commit/?id=fcf3076aef8396f394de82dd13b7a470753e2e97 I wished there was a feature like that: Tell that something I want CONFIG_FOO and that something will enable CONFIG_FOO with everything needed for CONFIG_FOO.
