  Question:
  Is this using juju for direct deployment, or via Orchestra? -- Daviey
  
  Via Orchestra. I think the main thing to test is juju because of it's
  reliance on java with zookeeper. We don't need to discuss anything, just
  test and fix bugs. -- Robbie
  
  For juju to work on ARM, I am assuming that:
  
  1. ARM hardware will support IPMI for power management
  2. ARM hardware will support pxelinux emulation for boot
  3. cobbler's existing IPMI support will work with ARM IPMI
  
  Status:
  There are two modes of operation: running juju in a local environment, and running juju via orchestra. juju currently fails to run on ARM in a local environment, and I am working on this - but this is blocking me from clearing the first five work items. Now that I have three pandas, I can test juju via orchestra also. I expect either to clear the first four work items as soon as I get juju working like this, or to find a series of ARM-specific bugs that I will need to fix first.
  
  Work Items:
- [racb] Investigate running an ARM-based juju environment †₁: INPROGRESS
- [racb]  Test juju/java/zookeeper on ARM †₁: INPROGRESS
- Investigate running the juju provisioning agent on ARM †₁: TODO
- [racb]  Investigate running the juju machine agent on ARM †₁: TODO
- [racb]  Investigate juju and ARM on LXC: INPROGRESS
+ [racb] Investigate running an ARM-based juju environment †₁: DONE
+ [racb]  Test juju/java/zookeeper on ARM †₁: DONE
+ [racb] Investigate running the juju provisioning agent on ARM †₁: DONE
+ [racb]  Investigate running the juju machine agent on ARM †₁: DONE
+ [racb]  Investigate juju and ARM on LXC: DONE
  [racb]  Validate juju using orchestra: TODO
  [racb]  Validate cobbler enlistment works: TODO
  Validate IPMI on hardware: BLOCKED
  [racb] Validate PXE booting via uboot: DONE
  Investigate juju with qemu-system-arm for testing ‡₁: POSTPONED
  Binary image deployment with PXE on ARM ‡₁: POSTPONED
  
  †₁: seems to work in local environment, cannot fully test until juju fully working on ARM
  ‡₁: no longer relevant
