I can't, of course, even contemplate the possibility of disagreeing with
RGB. Having said that, we (humans) do install complex tools and automated
constraints on each and every technologically advanced piece of equipment,
from cars and aircrafts, to computing machines (and we do not assume that
proper training and human interaction suffices to guarantee proper
operation of the said equipment). In this respect, methods like allocating
(in a controlled manner) exclusive rights to compute nodes do appear
sensible. I agree that installing restraints is a balancing act between
crippling creativity (and making power users mad) and avoiding equipment
misuse, but clearly, there are limits in the freedom of use (for example,
you wouldn't add all cluster users to your sudo list).
My twocents,
