This is not a full portage configuration. It contains only those parts that are necessary to set up a gentoo github mirror based sync system:
- Configures Portage to sync via https://github.com/gentoo/gentoo.git URL.
- Updates metadata-cache.
- Updates the dtd directory.
- Updates the glsa directory.
- Updates
projects.xmlfile - Updates the news directory.
If you want your overlay metadata caches to be automatically regenerated as well, do:
chmod +x /etc/portage/repo.postsync.d/sync_overlay_cache
