SmartOS's LX branded zones seem kind of cool to me, and may hit an interest point for you. Basically, SmartOS is an OpenSolaris variant where they use Solaris Zones for docker images, but they've implemented a Linux syscall table API so you can create Linux "compatible" containers from a Solaris kernel (and also full access to ZFS, etc). You can see a talk here[1] where Bryan Cantrill goes over the reasons you might want to use containers, SmartOS and how LX branded zones. Warning though, he's an
extremely engaging speaker, so not only are you likely to watch all of that 40 minute talk, but you might feel like binging on some other talks of his, so here you go.[2]
