Docker, the Linux container runtime: now open-source
The more I look into freebsd, the more I realise how awesome it is. This same thing has been in freebsd for ages: jails.<p>(maybe not the fancy deployment, but the container technology)<p>That, together with ZFS turns freebsd into one hell of a server OS. ZFS seriously needs to come to linux. And don't say license problem, "there is nothing in either license that prevents distributing it in the form of a binary module or in the form of source code."[1]<p>[1] <a href="http://zfsonlinux.org/faq.html#WhatAboutTheLicensingIssue" rel="nofollow">http://zfsonlinux.org/faq.html#WhatAboutTheLicensingIssue</a>
