>Description:

nice(1) does not work with SCHED_M2, nor as shell builtin using
nice(3) or via renice(8) or top(1) or other familiar tools.

I understand that I'm supposed to use schedctl(8) somehow instead,
unfortunately none of the application software that expects posix
niceness to work when launching jobs shares this understanding.

Not obeying niceness standard interfaces is a regression, even if
these are to be reimplemented somehow over schedctl.

>How-To-Repeat:

Try to nice processes, or have batch schedulers start background
processes with non-default nice values.

>Fix:
