[ewg] Allowing ib dignostics to be run without being logged in as root.

[Informatix solutions]

The issue is that it is entirely dependent on the security integrity of the
application with the setuid bit set.
If someone can insert code, or swap a dynamically linked library with their
own alternative, it becomes possible to have your own code executed as root.
The system is then completely compromised.

Then perhaps that is a safer way to do it, but it would put more work
on the system admin to set it up for people, but if setting the permissions
of the commands to setuid root opens up a security hole, we would not want
that.

Does anyone know if setting the permissions to setuid root does actually
open up a security hole ?
