Not a joke. I knew they used to use a pile of janky shell scripts for their init system. I didn't know they still do. That's disappointing.
And cesarb is correct - the issue isn't scripts; it's shell scripts, especially Bash and similar. Something like Deno/Typescript would be a decent option for example. Nushell is probably acceptable.
Even Python - while a terrible choice - is a better option than shell scripts.
