Bug 503974 – EXPERT depends on DEBUG_KERNEL

• Product: Gentoo Linux
• Status: VERIFIED UPSTREAM

[Description locozenoz 2014-03-09 11:57:07 UTC]

Editing init/Kconfig every update isnt funny.

[Comment 1 Samuli Suominen (RETIRED) 2014-03-09 12:16:17 UTC]

Missing kernel version and patchset information. Missing emerge --info output. Missing details of the exact problem.

Kernels sys-kernel/gentoo-sources-3.12.13 and sys-kernel/hardened-sources-3.11.7-r1 at least.

I find posting emerge --info pointless.

The problem is that CONFIG_EXPERT depends on CONFIG_DEBUG_KERNEL without a reason, and the dependency should be removed.

I guess you get to complain to Linus.

This bastard quote-generator wont listen to me.
I am asking if we can do it as a Gentoo-specific patch.

    [[ /usr/src/linux-3.14-rc5/init/Kconfig ]]

    menuconfig EXPERT
        bool "Configure standard kernel features (expert users)"
        # Unhide debug options, to make the on-by-default options visible
        select DEBUG_KERNEL

Note the comment in the middle of that config block, it depends on it as a reason; hiding such options from experts would be [insert Linus-style expletive].

You can automatically patch the file if you want, it can be done like this:

    [[ /etc/portage/env/sys-kernel/gentoo-sources ]]

    post_pkg_postinst() {
        echo

        # Place your sed call here (change in /usr/src/linux-${PVR}-gentoo/). 

        elog "User patches applied."
    }

Yeah, but isnt it up to experts whether to see something or not?

You can only see as much as you know about.
