Description of problem: Manual Partitioning shows two instances of Fedora 20, probably because btrfs root has been snapshotted, and hence there are in a sense two Fedora 20 installs. But this is going to cause problems if root is snapshot 50x as is semi-planned with the rollback project. This may also be occur with thinp snapshots. Version-Release number of selected component (if applicable): anaconda 20.21-1 How reproducible: Always if there are snapshots of root. Steps to Reproduce: 1. Install Fedora 20 once. 2. Sometime later, make a snapshot of its root subvolume. 3. Rerun the installer. Actual results: Two Fedora 20 installations (or as many as there are snapshots it seems). Also, no differentiation between what are separate/unique Fedora installations vs snapshots. Expected results: We either need fs metadata to help distinguish between separate installations and snapshots, with a user interface that indicates such. Or maybe some kind of installation specific UUID, then if anaconda sees multiple subvolumes with the same UUID it knows they're not unique. Additional info: Cosmetic issue, but will result in user confusion if there are automatic snapshots per: http://fedoraproject.org/wiki/Changes/Rollback

Oops. http://fedoraproject.org/wiki/Changes/Rollback is rollback via thinp snapshots. Untested to see if the problem reproduces there. The current one for btrfs seems to be: https://fedoraproject.org/wiki/Features/OfflineSystemUpdates
