openQA installer tests of today's Rawhide nightly - Fedora-Rawhide-20161116.n.0 - all crashed with:
ValueError: Namespace BlockDev not available for version 1.0
in a traceback that points to:
in blivet/util.py . See e.g. https://openqa.fedoraproject.org/tests/48712#step/_boot_to_anaconda/8 .
This is an automatic F26 Alpha blocker as it prevents all installer images from booting to anything useful.
Sorry about this, I somehow expected the useless calls that just prevent stupid warnings being printed to stderr would just consider 2.0 a higher version than 1.0 and move on. Blivet works with both BlockDev-1.0 and BlockDev-2.0, but that's impossible to tell to that stupid function unless we add more useless code trying to call it twice.
This is OK now, install tests are mostly working.
