<i>&gt; Have you considered using rkt as an alternative to docker?</i><p>I have, and I respect it a lot more--and CoreOS in general has struck me for quite some time as being the adults in the room in this space, I think the value prop remains very shaky but I appreciate that CoreOS seems to <i>give a damn</i>--but I don&#x27;t have a lot of use for rkt in general. The only place I have any multi-tenancy, I&#x27;m using FreeBSD and jails. (I&#x27;d like to use Illumos or OpenIndiana, as I better understand that stack than I do FreeBSD, but cperciva has done a great job with FreeBSD AMIs on AWS and I don&#x27;t have the bandwidth to maintain an OpenIndiana AMI.)
