Since allowing sudo nice
is pretty much the same as granting root permissions, I would not consider doing that.
I see two possible solutions:
1/ Allow the full command via sudo and pin it's parameters, like:
%nicegroup ALL=/bin/nice --20 /bin/whatever
But that works only if it is always the same program that needs nice'ing.
2/ Allow only renice
via sudo like this:
%nicegroup ALL=/bin/renice
The users then need to start their program like always and afterwards manually renice it via sudo /bin/renice 20 -p $PID
.
That is manual effort, but it can be scripted to be automated.
No, there is not. nice
is one of those commands that will run the process given in its own context - that is, if you allow sudo nice
, any commands passed to nice
will be executed as root. It may be possible to use /etc/limits.conf
and use nice limits that way and run the script you want to be higher/lower priority, but it doesn't help with renice
.
