958partition that can boot

960from a

962partition, and install bootstrap code into it.
963This partition must be larger than
964.Pa /boot/gptboot ,
965or the GPT boot you are planning to write, but smaller than 545 KB.
966A size of 15 blocks (7680 bytes) would be sufficient for
967booting from UFS but 128 blocks (64 KB) is used in
968this example to reserve some space for potential
969future need (e.g.\& a larger
