    @jaypatelani Interesting, but FreeBSD had jail development merged in 1999 with the official release in 4.0 (2000). When creating Jails for NetBSD did the project simply clone their features or has the project examined FreeBSD’s implementation and design out their limitations / misfeatures? I don’t know for a fact what these are, but after 26 years of modifications I’m assuming that some have most likely been discovered or arisen.

    I see that the project has considered earlier attempts going back to 2008 to add jails to NetBSD but no references to alternate approaches to lightweight virtualisation on other operating systems such as FreeBSD jails, Solaris Containers (via illumos) and SmartOS’ refinements.

    I’d be happy with either

    * a clone so I could easily port FreeBSD jails to and from NetBSD or

    * improved jails, e.g. enhanced secmodel as provided by secmodel_jail but would really like to know what I would be dealing with.
