Where to install programs? NixOS configuration, home manager, nix shell in repositories? (lm.paradisus.day)

My understanding is like this. For multi-user computers, you'd manage packages with home manager. If you're developing a project or need some kind of specific built tool or dependency, define in it in a flake.nix or shell.nix or build.nix in the project folder. And for single user computers, or maybe admin accounts install at NixOS configuration.

Whats the intent for each location? The current question Im asking myself is "why install home manager when Im on a single user instance and can just update configuration.nix?"

Home manager manages dot files, which aren’t managed at the Nixos config level. Sine this means managing the version of the corespondent package related to a dotfile config, home manager has to manage packages.

So, in my world: the only thing in home manager are programs which have dot files that need to be managed… everything else is in the Nixos config level. Except for local dev environments, which have flakes associated with them.

Have you ever found yourself installing something at the OS level, then realizing you'd want to customize it and moved it to your home manager installation?

I hadn't considered configuration. When I browse through the home manager options it's obvious just how many more settings can be set and tweaked. Thanks

I wish you could config defaults for zsh/nvim in the Nixos config. I have some servers that are generated from a config file and then meant to not be managed after that (so I build a sd card for them and insert card and they are booted into a working system. If a configuration needs to change, the idea is that I rebuild the sd card rather than rebuild on the server.)
