That is why Root is disabled on OS X, and SUDO is implemented.
Well aware of that. I will remind you however, that there's no real implementation of that within OS X (Aquafied, not Darwin). There's no equivalent of sudo and all (admin) users are 99.999% root. Scary but true.
As I said, you offer good advice for the average user. I amnot the average user. I'm comfortable with how I run the show and to date think I do a excellent job at protecting my users from themselves.
But thanks for the lecture.
I would also point out that in the context of this question, 'what is a sleepimage and can I nuke it?', has been pretty well covered. The tangets that have been taken into security is noted, but not necessarily needed to be further flogged.
