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.
I maintain some software, and Nix is by far the hardest to deal with. To package config files are relatively complex, and to submit a package you have to download the entire Nix repo, which is huge. Getting a package to build correctly can be a challenge.
It’s a pretty large ask for software contributors, who may have to iteract with a half dozen different distros. Now, you could say, leave it to the distro people to do the packaging, but it remains a barrier for entry and is by nature exclusive.
I don’t use NixOS, so I have little motivation to stay conversant with Nix and, frankly, it’s so demanding I don’t bother anymore. I can make RPM, deb, and aur packages trivially, and without having to hold Gb of some package repo (which I otherwise don’t use) on my disk.
git clone --depth 1will clone a git repo without older stuff. Without this, the nixpkgs git repo is like 13-14 GB, but with a depth of 1, it’s only 200 mb.
