Doing a whole system update via web is pretty nice. pkg image-update creates a clone of your current ZFS root and updates that. Whether the update fails or you actually want to continue working as if nothing's happening, both is no problem. Reboot and the updated ZFS root is active.
This is called boot environments and can also be managed manually using beadm. Personally, I've set up the system as I expect it to be after a reinstall and customization, then cloned a BE from it. If something fubars, I can either boot that or better, create another clone from it and preserve the original.
From the management standpoint, it's pure joy.
