When reporting installer problems related to storage it would be useful to have blivet version available in the logs along with anaconda version. If the installation succeeds, python-blivet is not installed on the system and I have not found information about its version.
There is a string in storage.log along the lines of "resetting Blivet (version 1.15)"
Oh, I see. Except it is sort of hidden there. It may be obvious to you, but moving it to a more prominent position would save trouble to bug reporters.
