How to add this repo using layman ================================= sudo layman -f -o https://git.backbone.ws/linux/overlay/blobs/raw/master/layman.xml -a backbone Using Backbone's Profiles ========================= Default Desktop/Laptop Profile ------------------------------ /etc/portage/make.profile/parent: /var/portage/portage/profiles/default/linux/amd64/13.0 /var/portage/layman/backbone/profiles/desktop Extreme Desktop/Laptop Profile -------------------------------------------------------- Warning! Using this profile is unsafe as it could lead to undefined behaviour of several packages! Not all packages are ready for the profile. Look at profiles/extreme/profile.bashrc for the exclusions I've added. /etc/portage/make.profile/parent: /var/portage/portage/profiles/default/linux/amd64/13.0 /var/portage/layman/backbone/profiles/extreme Hardened Server Profile ------------------------------ /etc/portage/make.profile/parent: /var/portage/portage/profiles/hardened/linux/amd64/no-multilib /var/portage/layman/backbone/profiles/server Repositories Priorities ======================= My /etc/portage/repos.conf/gentoo.conf: [DEFAULT] main-repo = gentoo [gentoo] sync-type = git priority = -1000 [local_overlay] priority = -999 [backbone] priority = -999 Remarks ======= For Desktops/Laptops I'm using backbone-sources: https://redmine.backbone.ws/projects/backbone-sources/wiki/Wiki.

For finding cruft files I'm using app-portage/findcruftfiles (do filter output carefully).
