Colin Walters 051cdf396c lib/checkout: Rename disjoint union, change to merge identical files ... It turns out that librpm automatically merges identical files between distinct packages, and this occurs in practice with Fedora today between `chkconfig` and `initscripts` for exmaple. Since we added this for rpm-ostree, we basically want to do what librpm does, let's change the semantics to do a merge. While we're here rename to `UNION_IDENTICAL`.
