Sun was ahead of its time in many ways. I used a Sunblade and never thought of it again until this article and its relation. Interesting.

I've thought a lot about zones and Docker. I remember booting a zone for the first time on Solaris (copies the kernel) and was amazed at how fast it booted. It had a lot of the same things (volumes that are mounted). I used to explain Docker as Solaris zones sometimes but no one knows what Solaris is.
