We just introduced a new release criterion and [associated test case](https://fedoraproject.org/wiki/QA:Testcase_base_edition_self_identification) requiring that Editions self-identify correctly (and that non-Editions do not identify as an Edition). It should be feasible to automate this test case, as its requirements are precise and relatively targeted. We can create needles for the Edition logos and check that the Edition installers do include them, and the non-Edition installers we test (Everything, KDE live) do not (and maybe also check they match a generic Fedora logo needle).

The `/etc/os-release` bit is of course easy to do.
