-To create a simple, non-redundant pool using a single disk device:
+Create a GPT partition on an empty disk first.
+Then add a partition of type `freebsd-zfs` from which a single, non-redundant pool is created:

....
-# zpool create example /dev/da0
+# gpart create -s gpt ada1
+# gpart add -t freebsd-zfs ada1
+# zpool create example /dev/ada1p1
