So I’ve recently taken an interest in these three distros:
All of these offer something very interesting:
Access to (basically) all Linux-capable software, no matter from what repo.
Both NixOS and blendOS are based on config files, from which your system is basically derived from, and Vanilla OS uses a package manager apx to install from any given repo, regardless of distribution.
While I’ve looked into Fedora Silverblue, that distro is limited to only install Flatpaks (edit: no, not really), which is fine for “apps”, but seems to be more of a problem with managing system- and CLI tools.
I haven’t distro hopped yet, as I’m still on Manjaro GNOME on my devices.
What are your thoughts on the three distros mentioned above?
Which ones are the most interesting, and for what reasons?
Personally, I’m mostly interested in NixOS & blendOS, as I believe they may have more advantages compared to Arch;
What do you think?

Oh 👀
I didn’t know that; I knew you could modify the underlying system, but doesn’t that result in new A/B snapshots, or something like that?
Sure, but I’d like to have a more seamless experience, i.e. not having to open/start any “containers” or something like that.
Also, can I “normally”/traditionally install software on NixOS, e.g. through Steam?
Listen to the “Linux User Space” podcast, episode 404. They explain every immutability model af of now. Ubuntu Core is missing.
Ubuntu is creating something new, looks really great but based on snaps, which are not bad packages but rely on a nonfree store that cant be replaced. So meh.
I’ve made the opposite experience. There were loads of snap-specific issues when I used ubuntu. So many that I now recommend not using ubuntu just because of snaps.
Thanks for your suggestion, but I’ll never use snaps/snapcraft/snapd by choice;
I do see the reasons for why developers/app maintainers may want to (universally) package themselves, but we’ve got Flatpak for that.
Less loopback devices = better imho
Agree partly. Maybe snaps are bad, dont know the details, but if system packages and even the kernel can be packaged, thats pretty nice
VanillaOS and BlendOS also use containers to install apps, just like Fedora Silverblue. In fact, it’s easier to install native packages on Silverblue than it is on VanillaOS. Just set your terminal to start a container by default.
Depends on what you mean by traditionally. Steam works without needing any special setup by enabling it in your configuration, just
programs.steam.enable = true. There’s also imperative package management with nix profile (don’t use nix-env -i which you will probably come across, it’s broken by design). Personally though I recommend sticking with the declarative configuration and nix-shell which temporarily brings packages in scope for the current shell only.what do you mean by that?
nix-envis used to install packages in a similar way toaptoryum- you install a package, it gets downloaded and installed. This way of installing goes pretty much against the whole idea behind immutable systems.The clean way is to add a package to your configuration file (and reconstruct your OS from that), or use a
nix-shellif you need the package only temporarily.Oh, ok
So I should reinstall the OS every time I change my config?
Is this like the “deployments” from
rpm-ostreein Fedora Silverblue?You just run
sudo nixos-rebuild switchand it makes your system match whatever is in your configuration file (packages, services, hardware drivers, config files etc.).There’s two different ways of identifying a nix package: its attribute path in the package set, and the name it self-identifies as. Here’s an example where those differ, firefox-esr. Its attribute path is firefox-esr while the package name it reports is firefox.
It’s very fast to find a package by its attribute path since that’s essentially one or more map lookups. In contrary, the package name isn’t unique (for example, firefox and firefox-esr both have a package name of “firefox” because they are built from the same package file just with different sources) and also doesn’t have an index, so to find a package with a matching name you have to search through the entire package set and evaluate every package to get its name and check if it matches.
nix-env -i searches packages by their package name, which as a consequence makes it slow and also unreliable since you might not get the package you were looking for, but instead another with the same name. nix-env -iA somewhat fixes this by installing packages by their attribute path, but even if you use that you get the same issues with nix-env --upgrade since that always searches for packages to update by the installed packages’ names (it might even replace one package with a completely unrelated one which coincidentally has the same name!).
The new nix profile however stores the attribute paths a package was installed from so doesn’t have any of these problems.
I think it depends on the user :P. NixOS is pretty hard to get into because the documentation isn’t great… but I’d argue it’s one of the most user friendly ways to configure a system, and it can be really nice to copy configurations from other people.
