JFYI

Installed another LDOM yesterday, ports have 2.02-2+sparc64.1 version
of grub2 package. Used it to install grub (still on sun partition
table disk), was unable to boot with error message:

# grub-install --skip-fs-probe --force /dev/vdiska
...
# reboot

{0} ok boot disk

booted from cdrom into rescue, downloaded old version of grub2 package
from [1] and installed grub with grub-install. After which I was able
to reboot to OS.
