Sorry. Innovation? no. Making headway? Absolutely not. Catching up? Not hardly.
Okay, let up be serious here. "sudo" has been around for a while, a long while. I've used it since *BEFORE* 1998.
At least Microsoft picked a good model to "embrace and extend". They did muck it up quite badly. They "re-thought" the interface ... badly. They made it complicated. They made it cumbersome.
Oh well, at least it is in the right direction. 10 steps forward, 9 steps and a few inches of a skid back again.
