On an rpm-ostree system, /var/lib/rpm is a symlink to /usr/share/rpm.
And that's only because I wanted to avoid depending on a small patch
to rpm to have it look in /usr/share/rpm automatically if /var/lib/rpm
If you follow this, you'll realize this also means it's immutable - rpm is
not involved in the upgrade process. When you download a new tree,
you also download an entire new copy of the rpmdb. And yes, it's an
efficiency hit. On the other hand, every upgrade is atomic.
