One of the goals I have for Atomic Host is that we are doing more integration testing work than the traditional client-side package assembly model.
However, in order to achieve that goal, we need to enable developers to quickly and rapidly test combinations of packages and code. Until now, actually developing on Atomic Host has certainly been *possible*, but not documented well and unnecessarily painful. I think with the new "ostree admin unlock" verb in OSTree v2016.4 that has changed: https://mail.gnome.org/archives/ostree-list/2016-March/msg00009.html Now v2016.4 is only in updates-testing, so we'll need to rebase to it, per https://fedoraproject.org/wiki/QA:Updates_Testing # rpm-ostree rebase fedora-atomic:fedora-atomic/f23/x86_64/testing/docker-host ...
