This is "more" conformant to the spec, which says the protective MBR=20 should have only one partition which covers the whole disk.

This would probably mean modifying the gpt utility and module to mirror=20 the EFI partitions in the PMBR, controlled by a flag so that real EFI=20 machines don't get choked. --------------enig289831A78775945CD87CD84A Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFGboGKldnAQVacBcgRAlVrAJ0bZTsfRe+3Ydmbi4dsJMt4man6twCeP6OD wC1nzizf5G95YgR8pkwj7wY= =9nnm -----END PGP SIGNATURE----- --------------enig289831A78775945CD87CD84A--
