The distro-integration tag was added for fedora openQA to only run a subset of tests. However since it was added only a few new tests have been labelled like that and in general a normal contributor or even maintianer has no idea when to add this tag. We also have been seeing several regressions getting into fedora that these tests would have caught. As such I worked with Adam to enable all tests for fedora openQA so we actually have proper coverage. This has been working for a few weeks so I think we can dop these tags so upstream does not need to bother with them at all. https://pagure.io/fedora-qa/os-autoinst-distri-fedora/issue/373 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
