Description of problem:
Due to https://github.com/docker/docker/pull/6452, it's forbidden for btrfs storage with selinux in docker.
So file this bug to track the status.
Linking back to two relevant Docker GitHub Issues.
/me cheers for Eric Paris to squash this bug ASAP.
Similar problem with unionmount or overlayfs. See:
Lots of affected users chiming in on the relevant Docker GitHub Issue. Many have included debug/version info, if that's helpful.
No I think we can close this. We have a workaround now for people who want to use BTRFS and SELinux.
