Thanks to everyone’s responses!  Basically the two use cases are (0.) supporting multiple virtual servers, with each client running their own private instances of applications, per physical rack, using Illumos Zones- and/or FreeBSD Jails-like OS-level virtualization to keep those virtual servers completely isolated, without the redundancy of running a hypervisor (since the multiple tenants can share the same underlying kernel); and (1.) running multiple application servers on the same physical server, completely partitioned and sandboxed, so that I’d have the reassurance that if I spun up a virtual server environment (such as to work on bringing up a new application) and managed to royally spam the (virtual) system configuration or filesystem or software stack (or somehow all three), in the worst case I could just safely bail and cleanly wipe out that container and start over with as little impact as possible on the services running 24/7 in the other containers.  Was simply wondering if NetBSD had an equivalent before deciding between going the FreeBSD route or the Illumos (_e. g._, OpenIndiana or OmniOSce) route.
