I installed sys-process/schedutils-1.5.0 at had no clue how to use ionice. No manpage and no "ionice --help". Found http://linux.die.net/man/1/ionice Would be nice if something like that gets into portage ;)
ionice has been integrated into util-linux

Odd. When I submitted bug 202373, i first searched for "ionice" and got the "Zarro Boogs found" message.
