[atomic-devel] Concerns about pushing Docker 1.10 into Fedora23

[Josh Berkus <jberkus redhat com>]

Folks,

We were discussing the changes in Docker 1.10 at DevConf and became very concerned about the consequences of pushing it into Fedora23.  I don't think that users will be prepared for the upgrade process for existing images.  Basically, I can see two things happening to create some really unhappy users: (1) most of them ignore the update notice and then have a long outage when they restart Docker, or (2) some of them run the migrator, and for users with dozens of images it makes their system unresponsive until it's done.   There's also a bunch of API changes, which *supposedly* don't break backwards compatibility, but has anyone tested for this?

Is it worth considering holding 1.10 back until Fedora24?
