I have some games that seem to benefit from being renice'ed (as in, the "renice" command) to a negative "nice" value. However, to do so I have to fire up a root login.

I'm about ready to write a renice wrapper to be run setuid root which can search for the games in the output of the "ps" command and renice them accordingly, but I feel like I must be re-inventing a wheel.

Is there an existing way to let users launch certain programs with negative "nice" values, or re-nice them to negative "nice" values, without root privileges?

Only root or user from wheelers group can set nice value less than zero. Other users can only change it to above zero.
