Back before containers were all the rage and there were things like userspace linux and openvz and the like, I'd have friends of mine who were Solaris fans swear up and down that zones were Just Better, but never explain why.

Now Linux has cgroups and namespaces for things like network stacks and process trees and things like Docker are using them to do better containers and Solaris folks still swear up and down that Zones are Just Better, but I can't find a technical explanation as to what makes them better.

As a Solaris person who swears up and down that Zones are better than anything in Linux, can you explain what about the implementation of Zones makes them superior to using cgroups, namespaces, etc.?

Thanks!

Thanks for the detailed response! I'll take a look at that presentation!

My understanding is that zfs isn't in Linux because the GPL doesn't play nice with the cddl, rather than a technical limitation. But your point is well received.

Also, good luck with Triton. Looks neat.
