A per-user configuration.nix

[copumpkin]

If I'm logging into or setting up a new machine, I want reproducible machine configuration, but also reproducible user configuration. My software configuration, programs installed, nix profiles, etc. would all be great to maintain like anything else. The goal being to minimize start-up time when someone gets a new account or machine.

Has this been discussed/worked on?

Another benefit would be sharing of developer set-ups and such, the way many people put their dotfiles online.

For the programs you can simply have a .nix file with a set, and nix-env -i
file.nix.

I think you're looking for ~/.nixpkgs/config.nix. Recommended reading: https://nixos.org/wiki/Howto_keep_multiple_packages_up_to_date_at_once.

Having a per-user configuration.nix would also allow to define services on a per user basis (through your systemd user instance).

Also: fonts and env variables.

The main problem is about privacy. /nix/store is world readable. We as a
whole community should think about this problem more, because it's becoming
a bottleneck in the nix expressiveness.

@lethalman: /nix/store privacy is being worked on by @nbp.

[lucabrunox]

Any pointer about following the progress?

@lethalman: no idea. Perhaps in the sprint-sumup blogpost that is scheduled to be written on monday by @iElectric, or you may better ask Nicholas himself. From the beginning there was the world-readable assumption and giving it up complicates many things. In any case, you can never have real privacy against root.

NixOS/nix#329

[nbp]

This issue is being addressed by the pull request #4594, taking a similar approach as #4493 suggested. The ultimate goal is to be able to share as many modules as possible between NixUP and NixOS.

Is it possible to set the value of an attribute like programs.bash.promptInit per user?

[vcunat]

You could e.g. add code conditioned on $USER into the system bashrc or similar approaches, but IMHO it's typically more practical to have such things in per-user dotfiles and have some solution for managing those (e.g. some version control system).

[alexeymuranov]

@vcunat, i need to

source ${pkgs.gitAndTools.gitFull}/share/git/contrib/completion/git-prompt.sh

somewhere for a given user. I do not know how to do it in .bashrc, but even if it is possible, i do not think this would be a proper solution. Besides, i am sharing my home folder between NixOS and Ubuntu.

[vcunat]

@alexeymuranov: hmm, one can always do such things, though it may not be pretty:

source bashrc-common
if [ grep -q '^ID=nixos' /etc/os-release ]; then
    source bashrc-nixos
    # ^ containing e.g. source ~/nix-profile/share/git/contrib/completion/git-prompt.sh
else...

[alexeymuranov]

@vcunat, it turned out that in my case it was enough to set programs.bash.enableCompletion = true.
