While I am not a fan of Nix the language, it is no more insane than ansible or kubernetes yaml soups.

As for packages… nixpkgs is by far the largest repo of packaged software. There are very few things I haven’t found there - and they are usually not in any other distro either.

I switched to NixOS because I wanted a declarative system that isnt’t yaml soup bolted onto a genetic distro.

By 2022, my desktop system was an unmanagable mess. It was a direct descendant of the Debian I installed in 1997. Migrated piece by piece, even switched architectures (multiple times! I386->ppc-i386->amd64), but its roots remained firmly in 1997. It was an unsalvagable mess.

My server, although much younger, also showed signs of accumulating junk, even though it was ansible-managed.

I tried documenting my systems, but it was a pain to maintain. With NixOS, due to it being declarative, I was able to write my configuration in a literate programming style. That helps immensely in keeping my system sane. It also makes debugging easy.

On top of that, with stuff like Impermanence, my backups are super simple: btrfs snapshot of /persist, exclude a few things, ship it to backup. Done. And my systems always have a freshly installed feel! Because they are! Every boot, they’re pretty much rebuilt from the booted config + persisted data.

In short, declarative NixOS + literate style config gave me superpowers.

Oh, and nixos’s packaging story is much more convenient than Debian’s (and I say that as an ex-DD, who used to be intimately familiar with debian packaging).

SuSE in 1996. Then Debian between mid-1997 and late 2023, NixOS since.

I’m not a big distrohopper…

I do, yes. I’d love to use it, because I like Scheme a whole lot more than Nix (I hate Nix, the language), but Guix suffers from a few shortcomings that make it unsuitable for my needs:

• There’s no systemd. This is a deal breaker, because I built plenty of stuff on top of systemd, and have no desire to switch to anything else, unless it supports all the things I use systemd for (Shepherd does not).
• There’s a lot less packages, and what they have, are usually more out of date than on nixpkgs.
• Being a GNU project, using non-free software is a tad awkward (I can live with this, there isn’t much non-free software I use, and the few I do, I can take care of myself).
• Last time I checked, they used an e-mail based patch workflow, and that’s not something I’m willing to deal with. Not a big deal, because I don’t need to be able to contribute - but it would be nice if I could, if I wanted to. (I don’t contribute to nixpkgs either, but due to political reasons, not technical ones - Guix would be the opposite). If they move to Codeberg, or their own forge, this will be a solved issue, though.

Before I switched from Debian to NixOS, I experimented with Guix for a good few months, and ultimately decided to go with NixOS instead, despite not liking Nix. Guix’s shortcomings were just too severe for my use cases.

NixOS, because:

• I can have my entire system be declaratively configured, and not as a yaml soup bolted onto a random distro.
• I can trivially separate the OS, and the data (thanks, impermanence)
• it has a buttload of packages and integration modules
• it is mostly reproducible

All of these combined means my backups are simple (just snapshot /persist, with a few dirs excluded, and restic them to N places) and reliable. The systems all have that newly installed feel, because there is zero cruft accumulating.

And with the declarative config being tangled out from a literate Org Roam garden, I have tremendous, and up to date documentation too. Declarative config + literate programmung work really well together, amg give me immense power.

NixOS.

It is good for everything, if you invest a little time^[1] into it.

I self host my email, and I have one mailbox, but countless addresses. Everything that needs an email address, has its dedicated one. Not because of security considerations (if someone would get into any of my aliases, I’d be fucked either way), but because I find it easier to filter and manage.

Like,if I get an email to randomwebshop@, and it hasno relation to said place, I will know that they either sold my data, or were compromised. I can then route it to /dev/null, and then everyone who tries to spam that address will be gone from my inbox.

It also makes it easier to tag mail, because I tag based on a property that I control. No reliance on sender, subject, list id or anything that the sender controls.
