upgrade can delete running deployment
Last modified: 2013-03-05 14:12:33 UTC
If you do: $ ostree admin upgrade gnome-ostree This will delete the previous deployment, and the current deployment (what the user's running) will now be previous $ ostree admin upgrade gnome-ostree This deploys the new tree, and then attempts to remove previous (but this is the booted deployment!)
