+This partition must be larger than
+.Pa /boot/gptboot ,
+or the GPT boot you are planning to write.
+A size of 15 blocks (7680 bytes) would be sufficient for
+booting from UFS but lets use 128 blocks (64 KB) here in
+this example, in order to reserve some space for potential
+future need (e.g. from a ZFS partition).
