New comment by Logarithmus on void-packages repository https://github.com/void-linux/void-packages/issues/28728#issuecomment-782856539 Comment: @st3r4g yes, I mean that all major distros have this option disabled (because it interfers with `pulseaudio`, `jack` & `pipewire` in some way). Fedora, Debian, Ubuntu, Arch, Manjaro, etc. 5 years ago Lennart Poettering himself asked it to be disabled in Fedora, lol: https://bugzilla.redhat.com/show_bug.cgi?id=1229700 But Void has it enabled. Some months ago I've built my own kernel without `CONFIG_RT_GROUP_SCHED`, but the error/warning persisted. I was testing on `x86_64-musl`.
