The geli(8) man page mentions the /boot/ directory requirement, but omits the /etc/fstab >How-To-Repeat: Install FreeBSD onto a geli encrypted provider that was created with "geli init -b" Then copy only the /boot/ directory to the unencrypted area that you will use to boot. Boot the machine, and see the errors where it can't find the / partition to decrypt. >Fix: I have attached a patch that mentions the /etc/fstab requirement in the geli(8) man page.
