Still a nice paper!

Could that also have been done with Zones? In terms of the developer experience?

Seems to me Docker just thought about the develop-and-deploy pipeline differently.

I had done the packaging work (like what Docker has done) as part of experiments with Belenix. I used puppet and rpm5 (that I had ported to Belenix) to ensure idempotency, and used ZFS snapshots for the layers. Unfortunately, life happened and I did not take the work live.

Interesting, never heard of BeleniX. Funny how live turns sometimes. Docker was open-sourced because a PAAS company almost went bust and exploded.

Yes, technology wise, I think it could have been done; once I left Sun/Oracle I stopped paying attention, so I can't speak to what else was done later.
