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.

Why aren't more people using NixPKGs? (lemmy.world)

Distro agnostic packages like flatpaks and appimages have become extremely popular over the past few years, yet they seem to get a lot of dirt thrown on them because they are super bloated (since they bring all their dependencies with them).

NixPkgs are also distro agnostic, but they are about as light as regular system packages (.deb/.rpm/.PKG) all the while having an impressive 80 000 packages in their repos.

I don't get why more people aren't using them, sure they do need some tweaking but so do flatpaks, my main theory is that there are no graphical installer for them and the CLI installer is lacking (no progress bar, no ETA, strange syntax) I'm also scared that there is a downside to them I dont know about.

If you use any accelerated graphics (GTK4 anyone?), you cannot and must not bundle all your dependencies.

Conceptually, graphics drivers have two parts: The part in the kernel (e.g. amdgpu), and the part loaded as a library from the system into the application (e.g. Mesa).

Mesa - or any other GL/Vulkan implementation - is loaded from the system into the application as a library. Mesa relies on system libc, system LLVM (!!!!), a particular libc++, etc.

If you ship libGL (and LLVM etc), you must re-release your software with upgraded deps whenever new graphics cards are released (and should whenever bugs are fixed). Your software is literally incompatible with (some) newer computers.

For the proprietary Nvidia libGL - which, again relies on system glibc - you can't legally include it.

Flatpak solves this by separating out 'graphics driver libraries' as a unique type of runtime, and having a shitload of special rules & custom hacks to check the system libGL, open source or proprietary, maybe substitute a Flatpak provided libGL, with all the deps that libGL needs, and make it compatible with whatever app & whatever app runtime.

Actually correctly solving the libGL debacle is half the value of Flatpak to me.
