[Question] Learning NixOS

[chris-kruining]

Hi,

I am improving my nixos setup by taking a close look at your repo. I've copied a lot of code already, but now my build is failing with error: attribute 'mapModules' already defined on rebuild, this error is triggered on inherit (lib.my) mapModules mapModules mapHosts; in my flake.nix

I do not get why this error is triggering though. I mean nix itself probably already has the function, but it is loaded from lib.my right?

Do you have any idea what might cause this?

Edit: took me a bit to get pushing to my repo up and running again, so for context; this is what I have thusfar: https://github.com/chris-kruining/.files

Don't know if you noticed this, but you have two entries of mapModules. The second one should be mapModulesRec

[chris-kruining]

I as a matter of fact have not seen that, at all, despite me staring at that particular line for ages....

thanks!

It happens to the best of us! I encountered a similar issue yesterday too, where I'd accidentally forgotten to place PATH for cargo inside sessionPath instead of sessionVariables and it had me confused why nothing would work only to notice that I had wiped the path completely when setting it for cargo and later built on top of it. 🤦

Nonetheless, glad to help out! :)

alright, next question. with the config we have for all of our modules, how can I apply my config to multiple users?

for example, with my old setup I had also applied zsh with starship for root. but that is missing now, nor is git enabled for root.

[chris-kruining]

not looking for multi user per se, more wanting to also apply all my terminal stuff for root as well, so that whenever I do a sudo su I don't get dropped of a cliff.

[Icy-Thought]

Out of curiosity, why would you want to sudo su?

[Icy-Thought]

Also, you could always replace the home-manager bits with nix once since they do work system-wide. (iirc)

so that I change to the root user, so that I dont have to prefix all of my commands with sudo and fill in the password. and no, I don't need root for everything, but a nixos-rebuild needs sudo.

not all the config is compatible both ways right? I tried that with my old setup and ran into a lot of issues. But then again, I am a noob at nix so perhaps I was doing something wrong

[Icy-Thought]

but a nixos-rebuild needs sudo.

That's why I have my sysdate command, which translates to nixos-rebuild switch --use-remote-sudo --flake .#"$(hostname)" --impure.
And you can always just use `sudo !!~ (does not work in non posix compliant shells) to apply sudo to the previous command!

not all the config is compatible both ways right?

I honestly don't know, since I never spent any time in either sudo su or sudo -i. But I can come back on that one a little later today and see if I can get it to work.
