One of my favorite blog posts. I enjoy it every time I read it. I've implemented two C package managers and they... were fine. I think it's a pretty genuinely hard thing to get right outside of a niche.

I've written two C package managers in my life. The most recent one is mildly better than the first from a decade ago, but still not quite right. If I ever build one I think is good enough I'll share, only to mostly likely learn about 50 edge cases I didn't think of :)

The fact that the first entry in his table says that apt doesn't have source packages is a good marker of the quality of this post.
