Live Upgrade from nv_103 to nv_104

So last week I managed to Live Upgrade my ufs root to a zfs root and it all worked fine.
This week with the release of nv_104 it's time to do a zfs Live Upgrade.
Needless to say it worked a treat.
Here's the pertinent output.

I downloaded the iso image and mounted it loopback - no need to burn DVDs;
[root] deckard:/ # lofiadm -a /data/solaris/sol10/sol-nv-b104-x86-dvd.iso
[root] deckard:/ # mount -F hsfs /dev/lofi/2 /mnt

Don't forget to add the new Live Upgrade packages before starting work;
[root] deckard:/ # pkgadd -d /mnt/Solaris_11/Product SUNWlucfg SUNWluu SUNWlur
[root] deckard:/ # lustatus

**********************************************************************

The target boot environment has been activated. It will be used when you
reboot. NOTE: You MUST NOT USE the reboot, halt, or uadmin commands. You
MUST USE either the init or the shutdown command when you reboot. If you
do not use either init or shutdown, the system will not boot using the
target BE.

**********************************************************************

In case of a failure while booting to the target BE, the following process
needs to be followed to fallback to the currently working boot environment:

1. Boot from Solaris failsafe or boot in single user mode from the Solaris
Install CD or Network.

2. Mount the Parent boot environment root slice to some directory (like
/mnt). You can use the following command to mount:

mount -Fzfs /dev/dsk/c0d0s0 /mnt

3. Run utility with out any arguments from the Parent boot
environment root slice, as shown below:

/mnt/sbin/luactivate

4. luactivate, activates the previous working boot environment and
indicates the result.

5. Exit Single User mode and reboot the machine.
