    Did you ever get this sorted?  I'm trying to build and run on Buster and getting the following:

 Compiling httm v0.18.2 (/usr/local/cargo/git/checkouts/httm-06074a082ad4c88e/0375596)

The issue you seem to be having is musl uses a different value than glibc for its setpriority function (which you have ask "Why?").

FIX/MITIGATION: httm's pub fn nice_thread and pub enum PriorityType in mod crate::library::utility are actually dead code in the latest version, so you can just remove/comment out both, if you want.

Policy wise, this is a WONTFIX issue (because old compilers, old/different libcs, etc., I won't support), but I may just excise pub fn nice_thread, et. al., or comment out to avoid in the future.

Good luck getting it to build! Happy to try to help, but, as indicated, this config is unsupported and I reserve the right to say "Oops, sorry can't help."

Thanks for the explanation and guidance! Fully understand not wanting to support a million build variants.

I commented both nice_thread and PriorityType, built it inside a rust:slim-buster container, then copied them to my host and all seems to be working fine.

The image is available on docker hub as prplhaz4/httm:v0.18.2-buster for anyone looking...
