Description Chris Murphy 2013-10-04 18:19:50 UTC
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

There is one "in use" root subvolume and a snapshot of it (hence there are in effect two root subvolumes).

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
