There's almost certainly a good reason for doing it this way that I've forgotten in the mists of time. Some ideas that spring to mind: * This has been a standard Unix approach for as long as I can remember. I was doing this on HP-UX systems almost twenty years ago. * I can use the same method on my own desktop as I use on a larger system where I want to give rights to multiple people. * I only need to edit sudoers once. From then on I can control permissions simply by editing membership of the group (which can be done with a GUI tool as well as by editing the text file). > And I will have to learn a bit about the difference between 'su' and 'su -'. "su -" gives you a login shell. So it's as though you actually logged on as root. "su" just changes the user. It doesn't, for example, give you root's PATH. Let us know if you have any more questions.
