From <https://www.tumfatig.net/images/2017/Vultr-FreeBSD-ZFS-root-17.png> in 2017: > ZFS Configuration > > Enter a strong passphrase, … The same wording is used in the current installer for FreeBSD. Anyone who knows of OpenZFS support for encryption might, naturally, assume that it's a passphrase for OpenZFS encryption. Not so. Similarly, from <https://www.tumfatig.net/images/2017/Vultr-FreeBSD-ZFS-root-19.png>: > ZFS Configuration > > Initializing encryption on selected disks, … There's less potential for confusion, because OpenZFS encryption does not apply at the disk level, but only slightly less (because not all people will make the distinction). Generally: * need to review the appropriateness of 'ZFS Configuration' as a heading.
