This is amazing news - you can't restore from the OS X boot disk if you own an Intel Mac.
Not because the feature isn't there, but because there's a bug. A bug! If there's any place you don't want bugs it's in the system restore.
Disk Utility should let you drag your destination device to the destination field but a screw-up in the mode of the list of devices renders them as a text list complete with copy/paste menus. So you can't drag and drop - it just does a multi-selection! (see image)
I thought I was going mad until the truth dawned on me - it's broken.
The work-arounds in the article are completely unsatisfactory. Apple should offer a replacement bootdisk for download that just contains Disk Utility at the very least.
I'm glad time machine has been created - that might make up for a stuff-up of this magnitude. I had to mount the disk and restore the Users and Applications manually under a different user to get around this (it was necessary after getting a replacement Mac when battery problems made it DOA).
[Note: You might be able to create your own boot disk and fix the Disk Utility app problem by visiting tuaw.com and reading this post].
[Update 2: You can create an OS X install disk by creating a DMG from the OS X install disk using Disk Utility, remove unnecessary files from the install disk image, then use Disk Utility to restore the smaller OS X Image to a DVD-sized blank sparseimage (just ignore the error 22 at the end). I updated the Disk Utility as part of the process and before booting on the new boot disk - it still failed as above. So this process isn't worth doing and there isn't a way to do a restore.
