Even more fun is when it starts to build the source packages at boot-time.
Maybe the source backends shouldn't be allowed*, but use .tbz2 and .txz ?
* i.e. emerge --binpkg-only and portupgrade --use-packages-only, and just
fail if no such packages have been prepared from the ebuilds and ports...

After all, there is no method to install from .src.rpm and .dsc either.
(one has to build the binary .rpm and .deb first, outside of PackageKit)
