Since 7ab08ba3e5e6f161b93ff2b3b7d5b18dc7b44510, ionice requires a "scheduling". $ schedutils/ionice 123 ionice: scheduling for the COMMAND not specified As `ionice` is the sister of `nice`, I question why a certain prio/class is needed. What's wrong with not passing a certain prio/class? Second, doesn't this break existing scripts which rely on "123" being executed?
