Well, you need to be a priveleged user to increase priorities else you
end up reducing the priority of the command that you run with nice. A
fair share scheduler allows tailoring resource allocation (cpu
time for example) to processes (like whats mentioned above) - which
should help give preferential treatment to processes as required by a
user. Rather than specify exact priorities ( which a user cannot be
expected to be very good at guessing) it's much better to provide some
way where a user can say that some process needs greater percentage of
cpu time than the rest.
