Personally, I would not bother encrypting the OS data; there is nothing secret there, and it does have a performance impact. Plus it would provide ample material for a known-plaintext attack! What you can do is set apart a partition during installation where you are going to store your data, be it /home, /var/www or whatever. After installation, encrypt that partition with geli(8), newfs it and put the name of the *.eli device in /etc/fstab. That should make the startup scripts ask for the passphrase. Do not rely on a keyfile that resides on a disk in the machine (that would make encryption futile)! Use a passphrase instead.
