I am currently working on deploying a MAAS / Juju / OpenStack system. I came across a few questions that weren't clearly mentioned in the documentation.

1. Can the head MAAS Server / Cluster Controller also be a node? If not i don't want to waste a 32 core machine for this purpose alone.

2. Can nodes use NFS or iSCSI for storage rather than internal hard disks? I would like the nodes to boot from PXE and use network storage so they can be diskless.
