Grub Update for Those Who Upgrade From b_86 to b_93

Due to changes in the GRUB boot system, one must manually update the Master Boot Record (MBR) to include these latest changes. Failure to follow these instructions when updating from 2008.05 (build 86) to a later build will result in a system that does not boot by default and instead the original boot environment must be manually selected.

Update the GRUB configuration on your ZFS boot device(s) using the following command:

$ pfexec /mnt/boot/solaris/bin/update_grub -R /mnt

When you’re ready to boot into the updated boot environment, you can reboot(1M) or init(1M) as usual.
