Some things can be achieved with chroot and various other tools in
NetBSD, other things are not going to work with chroot. It's nothing to
do with GUI management, but the fundamental architecture of chroot.

I've started looking into this some time ago, as I wanted to partition
my applications into isolated zones, without using Xen or other
hypervisors. I don't use NetBSD for anything serious, so not concerned
about security implications at the moment, as this is mostly a toy

So it is mainly looking at what NetBSD provides to restrict and manage
resources (CPU and memory limits, Veriexec and other security
frameworks, Rump, mount_null and mount_union, QoS for disk and network
I/O, etc). Not quite sure how this will work out in the end.
