app-portage/portage-utils is required for the gkb2gs.sh to function!
The script gkb2gs.sh extracts the kernel config from sys-kernel/gentoo-kernel-bin and saves that into /etc/kernels/.
$ bash gkb2gs.sh -h
gkb2gs.sh saves the kernel config of sys-kernel/gentoo-kernel-bin in /etc/kernels/ to be used for building sys-kernel/gentoo-sources.
You can autoselect best visible versions of both packages:
bash gkb2gs.sh
Or, specify certain versions with following flags:
"-b" for sys-kernel/gentoo-kernel-bin
"-s" for sys-kernel/gentoo-sources which makes the use of "-b" mandatory
The following extracts =sys-kernel/gentoo-kernel-bin-5.15.32 config to be used for the best visible version of sys-kernel/gentoo-sources:
bash gkb2gs.sh -b 5.15.32
The following extracts =sys-kernel/gentoo-kernel-bin-5.15.32 config to be used for =sys-kernel/gentoo-sources-5.15.32-r1:
bash gkb2gs.sh -b 5.15.32 -s 5.15.32-r1
To print this help:
bash gkb2gs.sh -hTo use the current LTS Linux kernel (as of March 22th 2022) do the following:
- Create the directory
/etc/kernels - Add
sys-kernel/gentoo-kernel-bin -initramfstopackage.use. We just extract the config and don't need the initramfs. - Add the following to
package.accept_keywords:
sys-kernel/gentoo-kernel-bin ~amd64
sys-kernel/gentoo-sources ~amd64
- Add the following to
package.mask:
>=sys-kernel/gentoo-kernel-bin-5.16
>=sys-kernel/gentoo-sources-5.16
- Execute the script as root, e.g.:
