In any case, size isn't an issue for any of gptboot, gptzfsboot or zfsboot (unlike boot2). For that matter, why do we need both gptboot and gptzfsboot? It would be more convenient to have a single GPT bootstrap that handled both UFS & ZFS. --=20 Peter Jeremy --DocE+STaALJfprDB Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk5sm/0ACgkQ/opHv/APuIcyWwCfbdxvDaI8zXk3L1w/hdP80Na6 wvQAoIy9I0uo8zGSl1UVKkU6CnEZU/o4 =3x7/ -----END PGP SIGNATURE----- --DocE+STaALJfprDB--
