Description Coacher 2012-12-13 12:33:50 UTC
Currently, genkernel checks whether CONFIG_FIRMWARE_IN_KERNEL option is set to "y" and if so it doesn't install in-kernel firmware. I want neither to compile firmware directly in the kernel image nor use firmware shipped with kernel sources, so I have linux-firmware package installed and CONFIG_FIRMWARE_IN_KERNEL is not set.

Therefore in my case genkernel will install blobs shipped with kernel overwriting files shipped with linux-firmware which is wrong and unwamted behaviour. Please add an option to tell genkernel not to touch firmware at all.

Reproducible: Always

    FIRMWARE_INSTALL control option.
    Prefer sys-kernel/linux-firmware to be installed and used rather than
    always running firmware_install and overwriting the root copy.
    Defaults to FIRMWARE_INSTALL=no, with ebuild updated to RDEPEND on
    sys-kernel/linux-firmware, via IUSE='+firmware'
