I've installed MAAS and added 8 nodes with Ubuntu Server 12.04 amd64. I would like to build a cluster with Condor and centralized authentication with LDAP. I'm starting to think that MAAS wasn't a good starting point, but maybe I can fix that.
How can I add packages and repositories to all nodes? Is it by changing the .iso from MAAS server? Can I do that with Juju?
How to add users and groups to the nodes? How to change fstab on all nodes so it can use NFS? Can I also deploy a whole folder with a binary application?
