One problem I have working in such environments, is the inevitable type
of person who tends to be the one weilding root - including corporate
types honestly believing all the rubbish they're fed in M$ and non-M$
whitepapers on computer security.

But you'd be larted. The only real problem is lack of audit trail
(that's really the only problem in most cases) and that can be fixed by
using something like sudo, but see the caveat mentioned below. I prefer
allowing people to do their job with as few restrictions as necessary.

...and dangers of both. With sudo, it's very easy to overlook paths a
user can take to get at a shell (e.g. if you allow them to edit a file
but don't take in to account the fact that $EDITOR might allow them to
open a command shell). It's also easy to ignore this fact and think that
sudo will solve everything - so in that sense using sudo introduces an
extra - somewhat hidden - danger of general complacency.

We had one colo box where root was disabled, everything went via sudo
and it tried to stop people doing stuff like "sudo su". It becomes
completely unworkable and you end up pointing out that, while sudo works
great in almost all cases, sometimes you do need a root shell :-).
