Comment 13 Adam Williamson 2016-11-15 22:10:41 UTC 
This prevents all F26 installer images from reaching the Welcome screen, so it's an automatic blocker per " Complete failure of any release-blocking TC/RC image to boot at all under any circumstance - "DOA" image (conditional failure is not an automatic blocker)".

This is why most Rawhide openQA tests fail since 2016-11-08.
Comment 14 Adam Williamson 2016-11-15 22:11:14 UTC 
I think this is probably in libblockdev.
Comment 15 Vratislav Podzimek 2016-11-16 07:33:56 UTC 
This is caused by quite weird in 'dmsetup' utility's behavior. And it should be fixed in libblockdev-2.1-2.fc26 built yesterday.

Comment 17 Adam Williamson 2016-11-16 16:12:36 UTC 
Well, it's broken *differently* now:

https://openqa.fedoraproject.org/tests/48712#step/_boot_to_anaconda/8

ValueError: Namespace BlockDev not available for version 1.0
Comment 18 Adam Williamson 2016-11-16 16:13:36 UTC 
That just means blivet is requiring explicitly blockdev 1.0 but that is no longer available (because it's 2.0 now), right? Guess I'll file another bug.
Comment 19 Adam Williamson 2016-11-16 16:45:01 UTC 
Filed https://bugzilla.redhat.com/show_bug.cgi?id=1395791 . I'm not closing this yet as I *think* that one happens before this, so we can't technically be sure this is fixed yet.

Yes, you're absolutely right about this.
Comment 21 Adam Williamson 2016-12-09 19:16:48 UTC 
This is OK now, install tests are mostly working.
Comment 22 Adam Williamson 2016-12-14 16:53:39 UTC 
However, this is now affecting F25, as lvm2 (which ultimately contains dmsetup) got bumped in an F25 update. This affects folks building updated F25 images. Can the fix be backported to F25's libblockdev?
Comment 23 Adam Williamson 2016-12-14 18:39:57 UTC 
vpodzime says https://bodhi.fedoraproject.org/updates/FEDORA-2016-0510ab2764 should fix this for F25.
