ZFS-only installation of FreeBSD 11.0 from DVD

FreeBSD 10+ comes with a built-in ZFS-on-root support in its installer, but that one still uses the pesky “/ROOT” filesystem as well as mountpoint hacks for all top-level children like /tmp, /var, /usr and so on, all of which with no apparent benefit—or if there is one, it is horribly undocumented.  This article describes an alternative setup that does without any of those.

Disclaimer: This article is about clean installation of operating system, where “clean” means that, if you follow these instructions, all existing contents of the hard drives will be destroyed.  Do not follow these instructions except on an empty hard drives.  I shall not be held responsible for any loss of data.
