The vanilla-sources are unsafe to use on Gentoo. Many services have
stupid-easy root exploits, since we install tmpfiles entries by default
and OpenRC runs them insecurely:
* https://github.com/OpenRC/opentmpfiles/issues/3
* https://github.com/OpenRC/opentmpfiles/issues/4
I've fixed similar exploits when I've found them in /etc/init.d and
pkg_postinst[0][1], but they continue to be added to the tree. And there
is no fix for opentmpfiles.
The gentoo-sources aren't 100% safe either, but the exploitable scenario
is less common thanks to fs.protected_{hardlinks,symlinks}=1.
