alt Hacker NewsYes, that would be one potential solution. But I have certainly never done it and bet >99.999% of the world's use of sudo is through 'sudo'.
Plus you only need one slip-up and you're hosed. Even people who try to almost always use '/usr/bin/sudo' will undoubtedly accidentally let a 'sudo' go through. Maybe they copy/paste a command from somewhere (after verifying that it's safe of course) and just didn't think of the sudo issue then and there.
The real problem is that there should be at least 2 levels for sudo, one for installing software and another that really allows someone to compromise the entire system, both layers should be separate to mitigate risk. At least the most secure layer should allow you to perform secure recovering and diagnosis
