Thanks a lot Grift, this idea of shell script fits well with
what Daniel said, instead have the tool acts as sudo and to
many hardcode, it generates a script such as this you typed, that
can be used in many system to set upt this admin users.
I believe I can use some ideas from your script and put it into a template
script generate by sepolicy admin. I still need to dig a little more in your
script and Dan ideas.
