Relax. While I wouldn't recommend OPs approach either. But you're not particularly right either.
Exodus clearly states:
> Exodus is a tool that makes it easy to successfully relocate Linux ELF binaries from one system to another... Server-oriented distributions tend to have more limited and outdated packages than desktop distributions, so it's fairly common that one might have a piece of software installed on their laptop that they can't easily install on a remote machine.
Exodus is specifically designed for moving between different systems.
He is largely moving from the same base image. In the article base layer is `alpine:3.18` and the target image is `alpine:3.18` and in the latter part of the article `scratch` (less to zero conflict surface). One would assume those two would be coupled.
There are other technical merits to not doing what he's doing but you haven't listed any and dismissed his work. I'd venture if you actually knew what you're talking about you'd have better things to add to this conversation than "OS package managers handle dependencies for a reason."
Perhaps next time give some feedback that would help the writer get closer to a well-working exodus like solution. It's hackernews, "dont roll your own" discouragement should be frowned upon.
