This will be ignored, so let's make it very clear
people are doing something wrong. Motivated by a bug
in a build pipeline that injected `/var/lib/rpm` into an ostree
commit which ended up crashing rpm-ostree because it was an empty db
which it wasn't expecting.
It *also* turns out rpm-ostree is incorrectly dumping content in the
deployment `/var` today, which is another bug.
