Important to note that NixOS has both a rolling release and point release version.

Note that there's both the rolling unstable channel and a bi-annual stable release channel.

It's kind of funny because I'd put NixOS on a complete newbies computer for sure, and recommend it to an expert... But I'm less sure if I'd tell a random mid-intermediate Linux user to switch.

Like if Grandma wants Linux on their computer to do some internet browsing for some reason... I'd absolutely put NixOS on it because it's easy to manage the system for them... But somebody who is a little familiar with Linux already might be more confused about the differences. It's kind of the ultimate beginner distro and the ultimate power-user distro, but a bit awkward between those extremes, haha.

you have to have a lot of linux/programming knowledge to do even the simplest things like installing/updating your software

So, pretty much like any other distro

The features themselves are very useful for basically any user. Whether they are worth the non-standardness and issues that come with it is another question.

Solution without a problem. A cool solution but yeah.

To get it out of the way first: There are no financial issues. There are more than enough funds to continue operations as they are for a sufficiently long time.

What is actually happening is that a long time sponsor has indicated that they (understandably) no longer want to foot the huge bill of hosting the entire archive of binary caches ($9000/mo). Finding a more sustainable setup is what the community is currently concerned with.
There is no risk of operations shutting down any time soon, the NixOS foundation has funds set aside to continue even this unsustainable setup for at least a year. We just want to be more efficient with our and others resources going forwards.

That's what all this you might have heard of is about.

Btw, even if the binary cache were to go poof, we don't technically need it. NixOS is a source-based distro like Gentoo and source hosting is not a concern. The binary cache is immensely helpful though which is why we'd obviously prefer to keep it.

Indeed, why would I switch, already have been running NixOS for 10+ years.

I'll edit. That was clearly a stretch

I like using btrfs with Arch because of the snapshots. If an update breaks something I can just boot into a snapshot from grub keep using my PC and solve the problem later. It's very useful... yes... very... you should try it... come... try btrfs... it's warm and cozy... INSTALL IT!

NixOS is not immutable in the way Fodora Silverblue is, and way more declarative and reproducible than Ansible. But yeah it is not something you "need". Other distros work too, but NixOS is way more fun.

It is an immutable distro, altough it isn't image-based like Fedora's rpm-ostree.

NixOS basically replaces Ansible because the Nix package manager achieves the same goals already (configuration, deployment, ...).

But I agree, the work necessary to put into this non-standard distro makes it hard to recommend for a casual user.
