-Note that typically most repositories other than `gentoo` don't come with a pregenerated cache. It is a good idea to generate/update their cache every time they are synced. One way to do this, is by activating the `example` hook script that portage installs by default in `/etc/portage/postsync.d`:
-
-```
-cp -i /etc/portage/repo.postsync.d/example /etc/portage/repo.postsync.d/gen_cache
-chmod +x /etc/portage/repo.postsync.d/gen_cache
