I also do it. I usually use the graphical tool once or twice a release
and then find myself not able to do something that yum lets me do
automatically so go back to just yum. Then again I have been doing it
this way for about as long as James Morris. I find myself completely
frustrated trying to do stuff on a Mac or Windows box when the gui is
just spinning and I have no idea a) is it installing, b) is it
crashing etc.

I agree.. the corporate/government places I have dealt with usually
have to hack the code to get rid of it because it violates so many
policies its not funny.

I think the vast majority of users would love everything to run like
it was under Windows95 when you could just click on something and it
worked without a password or login or anything. For the envisioned
'desktop' model is there a reason to have multiple users for the
default? Is there a reason to have anything but root?

Actually I am asking this in seriousness versus grumpiness. A general
security policy needs to know why certain things are set beyond
ancient Unix history.

Ah, but a man's reach should exceed his grasp. Or what's a heaven for?
