From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I feel like I'm missing out by not distro-hopping (lemmy.ca)

I've been dailying the same Mint install since I gave up on Windows a few years ago. When I was choosing a distro, a lot of people were saying that I should start with Mint and "move on to something else" once I got comfortable with the OS.

I'm comfortable now, but I don't really see any reason to move on. What would the benefits be of jumping to something else? Mint has great documentation and an active community that has answers to any questions I've ever had, and I'm reluctant to ditch that. On the other hand, when I scroll through forums, Distro Hopping seems to be such a big part of the "Linux experience."

What am I missing?

The way I understand it is like this:

The grand theory of classic package managers is the idea that lots of programs all need the same core libraries to function. An analogy would be like noticing most construction jobs need nails. So instead of making everyone bring their own copy of nails, resulting in dozens of redundant copies of it lying around, they have a single nails package that everyone can use.

But there are different versions of nails out there. Each version picks up unique new features, and drops legacy ones. Recent builds may incorporate and thus require the new features, making them incompatible with old versions of nails that don't have them. On the other hand, some builds may still use and rely on legacy features of nails, and are thus incompatible with the new versions. You may run into a scenario where you want Software A that needs nails version 14+, but also Software B that can only run on nails v <13, and you just can't, because they don't overlap.

Additionally, there may just be a totally different competing package out there, screws, that does largely the same job as nails, but in a completely different way that is totally incompatible with projects that expect nails. So if you need Software C that relies on nails, but also Software D that relies on screws, you might cause problems by installing both.

What a distro is is essentially a group of devs declaring that they are putting together some specific list of libraries (like, say, nails v14), and then sculpting up a bundle of software around those specific libraries. Can't cope with nails v14? That sucks. No package for you, then.

In that sense, distros are differentiated by what libraries and other low-level system softwares are available to the programs you wish to install on them. If you want your program to be available natively on every distro, it needs to be compatible with every competing set of libraries each distro has elected to use.

It is possible to just say "fuck it" to the distro's built-in libraries, and instead bundling the specific version of nails or screws or whatever you project needs directly with it. Build your own with blackjack and hookers, as it were. That's exactly what Flatpak does, among others. But it's trading flexibility for redundancy. In the age of cheap and plentiful storage memory, many people think this trade is well worth it. But it makes many formalists cringe.
