archbox VS nixos-generators

I also found this project which streamlines the process a little https://github.com/lemniskett/archbox

you mean something like archbox? https://github.com/lemniskett/archbox

If you don't mind the storage penalty, it looks pretty convenient to set up an Arch Linux chroot and use packages from the AUR when you need to: https://github.com/lemniskett/archbox/blob/master/NIXOS_INST...

Nixpkgs itself is several times the size of the base Arch Linux package collection, and by ‘non-unique’ package count, Nixpkgs is also much larger than the AUR. In addition to Nixpkgs, you can find Nix packages in several community ‘overlays’ for Nixpkgs as well as Nix's own user repositories.

You can check to see whether everything you currently use/need is conveniently available for NixOS in a comprehensive-ish way through the combination of these two web search tools:

• for Nixpkgs/NixOS: https://search.nixos.org/packages?channel=21.05

• for NUR: https://nur.nix-community.org/

NixOS also includes native Flatpak support.

Fwiw, packaging most things for Nix is very easy. I left Arch in ~2010 because at the time the package management stack and default repos on Arch basically sucked compared to most distros I'd used and liked, and from then on I decided that if I wanted software that wasn't in my distro's repos I'd just package it myself. After taking a little time to learn the tools on whatever distro I was using, I never missed Arch or the AUR. Compared to other distros, packaging normal software from source is usually exceptionally easy on NixOS.

If I were you I'd just dive right in and hit Nix's channel on Matrix with the Nixpkgs manual in hand if I found something I wanted to use that wasn't already packaged. But you can fall back on the options outlined above.

Those Linode instructions are about installing an OS from an installation ISO from Linode's rescue mode. -- I'd consider that more a 'plus' to Linode that you get to be able to install whatever unsupported Linux on Linode's VMs. But, of course it's not as smooth as the officially supported images.

Sibling comment mentions that NixOS provides ways to build VM images (e.g. https://github.com/nix-community/nixos-generators has a generator specifically for Linode).

Another option is to use nixos-infect, which will replace a Linux distribution with a NixOS distribution. https://github.com/elitak/nixos-infect

> At that point, I feel like all of the repeatability gains are gone. If I want to spin up a fresh server, I have to read a guide and set stuff up by hand?

Just as with ansible, "git pull to deploy". You'd keep a copy of your NixOS configuration.nix somewhere else, and would be able to apply it later.

> it really does let me just get a new VPS and deploy to it very fast

Using a tool you're familiar with to get the job done is going to be faster than learning to use a tool you're unfamiliar with.

I believe much of the use of NixOS is for hobby stuff, and for personal machines. (c.f. "In what environments do you use Nix", Development (1242) vs Home Server (845) vs Production (386) https://discourse.nixos.org/t/2022-nix-survey-results/18983).

If you need to generate lxc container in NixOS then perhaps this repo might be useful: https://github.com/nix-community/nixos-generators this article uses it https://www.thedroneely.com/posts/running-nixos-linux-containers/

You might wanna check out nix-community/nixos-generators, it’s maintained by the same dude as Disko

You can look at nixos-generators for support code that well let you take existing configs and build a variety of bootable images from them.

You should take a look at NixOS Generators, it's a flake with configs to build common formats like ISO, LXC, Docker, etc. I use that to generate an ISO with my config, specifically the packages.iso section.

I am trying to make use of https://github.com/nix-community/nixos-generators to generate qcow2 images from a NixOs configuration. Since it will be used with Scaleway, they require an efi bootable image.

I haven't migrated machines from one vm provider to vmware, but I have provided a number of pregenerated nixos images (along the line of https://github.com/nix-community/nixos-generators) to clients to install onto vmware (and other - hyperv, xen, qemu, physical) hosts.
