I'm planning on, eventually, putting together a NAS for myself. I've basically narrowed down the selection to either trying NixOS or going for TrueNAS, however I can't figure out how to decide between those two, as they are fundamentally quite different.

TrueNAS is a dedicated NAS OS so that's obviously enticing for me, but I heard if you also want to do some server stuff like hosting some things and not just storing data it is subpar? I never got the information out of people what exactly is supposed to be subpar about it, but I've seen those complaints a handful of times.

Meanwhile NixOS is just a Linux distro. I'm familiar enough with Linux, although NixOS is its own beast and from what I heard its documentation isn't quite what you'd get out of for instance the Arch Wiki, but it being declarative and easy to restore old versions in case something breaks allegedly makes it rock solid, so that also sounds interesting.

So, after thinking about those things, I was wondering if any of you who use either of them could share your experiences and what you like or dislike about either option?

I'd avoid NixOS personally. It is to obscure of a Linux distros to be widely supported.

TrueNAS all the way. If you want something more you could virtualize it by picking up a extra Data/SAS card and passing it though to a TrueNAS VM.

Its been supported since the early 2000s.

By whom?

I'd rather stick with more standard tools. Ansible is a big one but there are other tools you can you to auto provision VMs.

NIXos is a cross-platform package manager for Unix-like systems, and a tool to instantiate and manage those systems, invented in 2003[6] by Eelco Dolstra.
