About Renice demanding monotonical increases
 
Hi

I was wondering why exactly renice doesn't allow normal users to undo decreases in priority to their own processes.
I know the man's talk about this but I didn't understand exactly why this constitutes a problem.
What exactly does it mean "administrative fiats"?

I suppose this security measure is to allow some sort of sophisticated attack.

From renice's man:
"Users other than the super-user may only alter the priority of processes
they own, and can only monotonically increase their ``nice value'' within
the range 0 to PRIO_MAX (20). (This prevents overriding administrative
fiats.)"

Thanks

What exactly does it mean "administrative fiats"?
My first thought was: a small (usually convertable) italian sportscar driven by politicians, however this def. is probably more accurate:
"an authoritative determination"

I suppose this security measure is to allow some sort of sophisticated attack.
More likely it's desinged to keep users from wreaking havok by changing nice values (like changing their goat porn downloads values to a -20 nice value)
