ionice and drop permissions

What's the proper way to start a process ionice'd as realtime but with the resulting process starting as a specific normal user instead of as root? 96.232.39.129 (talk) 00:39, 5 April 2022 (UTC)

The ionice program affects scheduling of I/O in Linux. See the Linux General Commands Manual [1] . Philvoids (talk) 17:31, 5 April 2022 (UTC)

Where we read "Realtime [...] This scheduling class is not permitted for an ordinary (i.e., non-root) user."  Card Zero  (talk) 18:09, 5 April 2022 (UTC)

ionice -c1 su linus -c /bin/whoami will run whoami with real-time IO as user linus LongHairedFop (talk) 18:36, 5 April 2022 (UTC)

Exactly what I was looking for, thanks.
