I hate packaging my software for Linux (fresh)

Just give the source away. Don’t package it at all (or at most, do so for your own distro). If your software is good enough, others will do the packaging for you. You’ll have to field a few inquiries, maybe, until someone steps up, but if you’ve got a canned response already written those don’t take long to handle.

This dev’s problems are twofold: first, he’s in too much of a hurry to get this thing out everywhere, instead of waiting for others to take the burden off him. Second, he wrote his code in Rust, which is difficult to package correctly in a self-contained manner because it tries to force you into using its own language-specific dependency system. He picked up a footgun and shot himself with it, in other words, and is now hopping around cursing.

But I thought rust was 100% safe and the best? /s

There’s nothing wrong with the language that I’m aware of, but some aspects of the ecosystem seem to have not been thought out with Linux packaging in mind, let’s say.

I’m just making fun of the people who treat rust like the next best thing after sliced bread and pretend it will make it so you have 0 bugs.

Well, that sounds really immature.
