Teuthology currently uses Chef to do some node configurations, but we're transitioning away from Chef in order to use Ansible. This work is in progress at https://github.com/ceph/ceph-cm-ansible
We want to remove some of the hardcoded values that are unique to our labs, like the "ubuntu" UID and the URL to gitbuilder.ceph.com.
We've ported a lot of the Chef settings, but we're not yet complete.
Please join us in the #sepia IRC channel in irc.oftc.net for discussion regarding the Ceph test framework and lab management.
