As sort of an addendum to this question, I've noticed that drives that have been cloned generally show the blinking question mark for an instant while booting up, just before they go to the Apple icon. I've always wondered why this is, and I'm wondering if the answer to this is the same answer as to why a Time Machine backup wouldn't work?
In the PC world of disk cloning, there is the concept of the SID (security identifier) that is randomly generated when a manual install is done for an OS, and when you dump a clone of an OS, you have the occurrence of multiple machines with the same SID, which can cause problems. You therefore need to use some type of "SID scrambler" in order to rectify the situation. I'm clueless how this goes on the Mac side, however, or if it's related to Mister790's question.

+Maybe the Time Machine backup has the same "SID" as the computer being used?
