New issue by st3r4g on void-packages repository https://github.com/void-linux/void-packages/issues/28728 Description: `rtkit` is basically a dbus interface to `sched_setscheduler`, which is not implemented on musl. Here is the reason why: https://github.com/MusicPlayerDaemon/MPD/issues/218#issuecomment-364320830 So it seems it should be patched to use the `pthread_*` functions instead.
