I don't think systemd has any concept of filesystems (volume formats). It gets all of this from libblkid, udev, and the kernel. So I'd say one of those three things is confused, and then confuses everything else. The fact you get a difference in output between lsblk and blkid is itself a bug. I'd file it against libblkid and then include the bug URL here. -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
