You can add this Git repository to be available from emerge:
Add this as /etc/portage/repos.conf/cwte-linux-repo.conf, and then you can update it with emaint sync -r cwte-linux-repo
[cwte-linux-repo]
location = /var/db/repos/cwte-linux-repo
sync-type = git
sync-uri = https://github.com/XerneraC/cwte-linux.git
From there you can install the cwte kernel by emerging sys-kernel/cwte-linux
You can load or modify the config by exporting
export CWTE_CUSTOM_CONFIG=1This will make the ebuild pop up the menuconfig dialogue before compiling
From there you can load the old config .config and modify it, or just load a different config alltogether
The edited config must replace the .config config
