I'm working on a DevOS-inspired setup with flakes + home-manager on Arch Linux. I'm using aconfmgr as a neat escape-hatch to manage config and packages in a fairly declarative manner.

I'm having some issues as I'm trying to switch from bash to zsh though. When i do programs.zsh.enable, I get an error about packages being in conflict:

...
installing 'home-manager-path'
building '/nix/store/4fb72177cs4brdrq6k7h6i9f3cvfyi17-user-environment.drv'...

Oops, nix-env failed to install your new Home Manager profile!

Perhaps there is a conflict with a package that was installed using
'nix-env -i'? Try running

    nix-env -q

and if there is a conflicting package you can remove it with

    nix-env -e {package name}

Then try activating your Home Manager configuration again.

I suspect the issue is that nixpkgs is providing one version of zsh while home-manager is providing another, but I don't see how that's possible or how to fix it. Here's my flake.lock file: https://github.com/d4hines/beth/blob/master/flake.lock

Any ideas?

Small little thought, but does anyone think that programs.bcc.enable might be good for the core profile? I'm starting to dive into these tracing tools after ignoring them for some years now, and I have to say, they are quite impressive

In reply to @princemachiavelli:matrix.org
Yea it would be nice. I just used a few of the tools a few days ago and some seem to be broken. The ones that use dtrace make sense since a lot of packages are not compiled with support. But I think there are quite a few that just need the right python packages available.

I don't think the version of nix shown contains my PR to fix zsh completions. Maybe you could try bumping to a more recent version of nixpkgs to get it?

In reply to @timdeh:matrix.org
You could make a simple overlay for nix-zsh-completions that replicates what I did and then renable completions if you want
