bootadm update-menu doesn't work with EFI-labeled disks
If you create root pool on EFI-labeled disk, bootadm update-menu can't handle this:
# bootadm update-menu -R /a -o /dev/rdsk/c2t0d0 bootadm: fstyp -a on device /dev/rdsk/c2t0d0 failed bootadm: failed to get pool for device: /dev/rdsk/c2t0d0 bootadm: fstyp -a on device /dev/rdsk/c2t0d0 failed bootadm: failed to get pool name from /dev/rdsk/c2t0d0 bootadm: failed to create GRUB boot signature for device: /dev/rdsk/c2t0d0 bootadm: failed to get grubsign for root: /a, device /dev/rdsk/c2t0d0 # bootadm update-menu -R /a -o /dev/rdsk/c2t0d0s0 bootadm: failed to determine fdisk partition: /dev/rdsk/c2t0d0 bootadm: cannot get (hd?,?,?) for menu. menu not on bootdisk: /dev/rdsk/c2t0d0s0 bootadm: duplicate command default at line 9 of /aboot/grub/menu.lst

The first invocation of bootadm looks wrong, but the 2nd one should work. I wonder why there is -z to indicate ZFS, it thought that was mandatory.
I do remember seeing some warnings from bootadm, but the menu was updated correctly. Is that the case here? Could it be that bootadm works despite spewing out warnings?
