It has already been said, but here's a recap. Most of what you'll find in /usr belongs to the current BE. Datasets create below zroot/usr, e.g. zroot/usr/local, magically appears as /usr/foo, e.g. /usr/local. The same goes for zroot/var and /var. If you want to install FreeBSD with ZFS using some other train of thought, then feel free to do so. I have my own set of scripts at http://ximalas.info/~trond/create-zfs/canmount/, and they certainly have their flaws, and maybe I even change these scripts in the future as I move along and change my perspective on FreeBSD and ZFS. > On 15 February 2015 at 13:52, John Goerzen <jgoerzen@complete.org> wrote: > > > Ben Woods <woodsb02 <at> gmail.com> writes: > > > > > > > > To quote Allan Jude when I posed this question to him: > > > > > > "The /usr dataset has 'canmount' set to off.

Just remember to take off any metal clips, etc.
