I suspect a lot of the NetBSD community would think it nice if we had
jails (like FreeBSD), or some kind of container. Your reference to
"Project/Kernel team", though, implies a higher degree of central
planning than exists. While there are some funded projects and things
that many think are important, jails just aren't that high on the list.
So, someone needs to look at all the container systems, design what
makes sense for NetBSD, and start an argument about it. Then someone
needs to write the code. (Or, if "let's have jails like FreeBSD" is
viewed as sensible, integratee the FreeBSD code.)
