When the installer reaches the disk partitioning stage, it will present
you with a list of options, one of which is "Shell." This will drop you
to a shell instance where you can manually create your partitions and
your zpool. A brief message will appear when you first enter the shell
with basic instructions:

1. Mount your custom partitions with /mnt as the root of the system. In
   this case, use the `-R /mnt` flag when creating the pool so your new
   root ZFS filesystem is mounted there.

2. Create a custom fstab file and place it in /bsdinstall_etc. I'm not
   sure how necessary this is if you aren't using fstab to mount any ZFS
   filesystems; that is, I don't know if the installer will try to stick
   its own fstab into the installed system if a custom one isn't present.

Once you exit the shell the installer will proceed as normal: installing
everything to the mounted disks/filesystems, adding users, etc. After
the installation, you'll want to choose the option to drop to a shell
again in order to edit /boot/loader.conf and /etc/rc.conf, make sure no
invalid fstab file has been installed (if necessary) and set the
"bootfs=" property on your new pool.
