I think that a lot of users tend to switch to using root because they
cannot achieve simple tasks with their "normal" user. For instance
writing cd's. It would help if there is a doc that explains how users
can best set up their system to achieve this. For example, hinting to
the use of sudo and so on. This would help IMO but i haven't found a 
doc that explains these issues and suggest sollutions for the most
common tasks where users are confronted with permission problems.

Such a doc should really be available alongside the other debian docs
on the site. Now everybody who runs into these kinds of problems 
tries to solve it their own way which aren't necessary the best: 
running as root, using SUID and so on.
