Commit e5dc681a changed EFI_NUMPAR from 9 to 128. This means that the
on-disk EFI label has efi_nparts = 128 instead of 9. The index of the
reserved partition, however, is still 8. This breaks
efi_use_whole_disk(), which uses efi_nparts-1 as the index of the
reserved partition.
This commit fixes efi_use_whole_disk() when the index of the reserved
partition is not efi_nparts-1. It rewrites the algorithm and makes it
more robust by using the order of the partitions instead of their
numbering. It assumes that the last non-empty partition is the reserved
partition, and that the non-empty partition before that is the data
partition.

Issue #808
Native ZFS for Linux! ZFS is an advanced file system and volume manager
which was originally developed for Solaris. It has been successfully
ported to FreeBSD and now there is a functional Linux ZFS kernel port
too. The port currently includes a fully functional and stable SPA, DMU,
and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./configure
$ make pkg
