PlanetLab Creates a More Advanced Sudo

angry tapir writes "Researchers at the PlanetLab global research network have developed a potential replacement for the widely used Unix sudo tool, called Vsys, that will offer administrators far greater control over what end users can and can't access. Vsys is similar to sudo, except it offers finer-grained access to system resources. PlanetLab created Vsys as a way to allow its researchers to access low-level network functionality so they could develop new network technologies — overlay networks, user-level file systems, virtual switches — while their experimental work remained safely isolated from other users."

You are missing the whole point of sudo...

Sudo is for letting unprivileged users issue specific administration commands without knowing or entering the root password.

I know what sudo does. That doesn't mean I like it. sudo is "for letting unprivileged users" ignore the existence of root, plain and simple. Bad idea.
