This sounds like a great improvement. I have read the sudo source code and anyone that seriously thinks there's no problem with it being SUID is crazy.

That said the whole security model of sudo makes no sense. As soon as you can access a sudoers' account you can trivially steal their password by MitMing sudo and waiting.

I think that is a bit strong. Sure, you aren't gaining much protection if you just allow sudo -su root but there are a lot of valid use cases.

  1. Logging.
  2. A bit of an "explicit" check to keep you from doing something stupid without thinking.
  3. You can configure sudo to only allow specific commands from different users. (Maybe a trusted friend should have permission to reboot your Minecraft server but nothing else)
