Since Fedora-Rawhide-20190816.n.0 - and including Fedora-31-20190820.n.4, so this is on Rawhide and F31 both - the openQA 'install_no_swap' and 'install_software_raid' tests are failing consistently on every compose. The failure seems to be when formatting the root partition, as XFS because the tests run from the Server DVD:

only those two tests are affected, for some reason (presumably something to do with the auto-generated filesystem layout - it may be to do with the root partition size, in fact, as it'll likely be bigger in those two tests than any of the others, now I come to think about it). I'll attach all other logs too.

anaconda changed in the compose in question, from anaconda-31.22-1.fc31 to anaconda-32.1-1.fc32. pykickstart went from pykickstart-3.20-4.fc31 to pykickstart-3.21-1.fc32 . pyparted, libblockdev, blivet and xfsprogs did not change.
