+partition, and install bootstrap code into it.
+This partition must be larger than

+or the GPT boot you are willing to write,
+a size of 15 blocks (7680 bytes) would be sufficient for
+booting from UFS, but let's 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).
