Since I’m already a NixOS user, I thought to check out Series 4. One of the steps was “install flatpak”
My disappointment is immeasurable and my day is ruined.
My disappointment is immutable
“install flatpak”
why would someone do that in NixOS? nix has a lot of packages and using flatpaks imperatively would lead to less reproducibility
My usecase is that I want to build a rock-solid workstation laptop for my non-tech-savvy family member.
I configure all the basics in .nix files, and then from there, they can install Flatpak from the software center, like they are used to doing.
Then I can just do a rebuild switch when I see them, make sure it’s all working, and then trust that they probably won’t break the system in-between.
Edit: to be clear, in my own config, if it’s not reproducible, I’m actively working to fix that.
I mean why would you be fully against flatpak? I use NixOS without it and always packaged natively on Arch, but especially when upstream offers flatpak, it makes sense to enable it. Keeps the user-facing programs up to date and somewhat sandboxed while you can have a stable release beneath it. Especially if the system’s actual users aren’t that tech-savvy.
Stuff on unstable tends to break, especially electron-dependent derivations. Stable doesn’t always have the latest and greatest. Flatpak seems like a good compromise for desktop applications in some cases.
Well the only real reason when it comes to Nix is that they aren’t declarative. For a lot of Nix users, the ability to describe every bit of software and all their settings in one giant config file is the draw. Not necessarily anything against Flatpaks themselves.
But I agree, I like being able to mix the two where it makes sense.
NixOS itself by default isn’t fully declarative anyways, nix-env for example is imperative and very comparable to flatpak regarding applications.
I welcome the efforts to move away from all imperative bits in NixOS though. My point was rather not to dismiss an article on NixOS for mentioning flatpaks.
Flakes takes care of a lot of the imperative bits, but some people are wary of them since they’re marked experimental.
I don’t think flakes can do much more declarative than “legacy” nix, rather they increase reproducibility and purity. Also their tooling doesn’t offer imperative stuff by default, but I’m not sure they cover use cases previously solved imperatively. E.g. I don’t think you can install user software through a flake. Sure you can create shells with software available, but that is also possible without flakes.
Maybe my understanding here is wrong though.
They cover a few things – most notably they replace channels, which are imperative.
Unless I’m way off, you can also install user software through flakes if you add them as inputs. That’s what I’m doing with Musnix.
You can also pull a repo and ‘nix run .#software’ from the command-line, without entering a shell. That’s how I’m using NixifiedAI.
I thought about doing that but updating nixos confuses me. Does
nixos-rebuild switchpull new packages? To my understanding there is a file that saves all currently installed versions of packages and switch only adds new things but wouldn’t update packages.Like, if I want to update Google Chrome. Doing switch wouldn’t change anything if the config hasn’t changed, right?
I believe that’s correct – if nothing has changed from your last generation, then the new generation will be identical. But if something has changed, it will do a bunch of duplicating and remapping symlinks in the Nix store to ensure that everything plays nicely together and that you can rollback to a previous generation if needed.
So if you do a rebuild switch regularly, you will end up with gigs worth of old “copies” of things that aren’t being referenced in your current generation.
That’s what nix-collect-garbage handles – once you know your current generation is working well, you collect the garbage and recover that space, at the expense of not being able to roll back.
That’s why I think building a core system with NixOS and then having user software come from Flatpak is a nice combo for simple workstation that won’t update and bork itself, leaving my grandpa without a laptop until I can come take a look.
Edit: To clarify, nixos-rebuild-switch won’t update your Flatpaks at all – just the Flatpak service
That makes a lot of sense. I can setup their computer with nixos and stuff that needs to be updated regularly (like a web browser) can be flatpak which should be more stable too.
Then
flatpak updatewould get them updated without rebuilding the whole OS.My grandparents have been rocking Linux Mint for a few years. I have managed Chrome through Flatpak since I discovered that was possible on Mint. I’ve been flirting with the idea of having NixOS instead so I don’t have to remember what I’ve configured in the past. I’m not 100% sure now though :-P
Exactly right. Throw in Plymouth and set the bootloader timeout to 0 and you’ve got a noob-friendly workstation.
Plymouth?
It’s a graphical boot screen.
Just helps eliminate all the bootloader noise you see when booting up or powering off that make scare off less tech-savvy folks
Ahh, itsfoss.com. they had some article on “being a supercharged Joplin user” or some nonsense and suggestion 3 or 4 was “Create a notebook”… Really being a power user when you’re utilizing the most basic functionality the app was created for…
