"While the FAQ is indeed clear, the installer's simplicity appears at that point a little deceptive, in that one (I know I was) is tempted to think that such a user-friendly installer would not harm one so easily..."
I disagree. I think the installer is fine the way it is and it was not the problem here. The problem was the original poster's too-cavalier approach to something that is well-known to be dangerous. What happened here is somewhat analogous to texting while driving or flying an airplane drunk and, when disaster occurs, being upset (assuming survival) that the equipment didn't prevent it. Had he prepared properly, backing up the system first and reading the documentation, he might not have made the error, due to the clear warnings in the docs, and if he had, recovery would have been easy from the backup. Putting additional hand-holding in the installer (what part of "Use whole disk" was difficult to understand?) can only add to a false sense of safety. I think it makes a lot more sense that limited development resources be devoted to real issues, as opposed to protecting people from their own carelessness. /Don Allen
