NetBSD disk wedge support.
* grub-core/kern/emu/hostdisk.c (grub_hostdisk_find_partition_start)
[__NetBSD__]: Handle NetBSD disk wedges.
* util/getroot.c (convert_system_partition_to_system_disk)
[__NetBSD__]: Likewise.
2012-02-03 Mark Wooding <mdw@distorted.org.uk>
* util/grub-mkconfig.in: Use umask rather than chmod to create
