rustysd!
I know that systemd is a VERY contentious issue for some people!
I have learned about rustysd today.
I don't fully understand what it does and does not do but it sounds to me like it is a service manager that can do a subset of what systemd can do, but it it is WRITTEN in Rust!
It is not the kind of software that I think I would use but maybe it is USEFUL for some people?
