Fea's NixOS Configuration Flake

This is the flake I use for configuring my main NixOS system on my laptop and hopefully soon my server as well.

Usage

This flake currently only exposes the NixOS configuration laptop.

In order to rebuild your existing NixOS system using this configuration, run

sudo nixos-rebuild switch --flake "github:feathecutie/nixos-config#laptop"

or an equivalent command.

Assumptions

This configuration currently assumes several things about the system it's used on:

• 64bit x86 CPU
• EFI-based boot
• FAT32 EFI partition with the partlabel EFI system partition (yeah still dualbooting Windows and afraid to brick Windows if I change that partlabel)
• btrfs partition with the partlabel nixos and the subvolumes nix (for mounting /nix) and root (for mounting /)

The configuration also currently sets passwords for the existing users that I won't be exposing here. I'll try to figure out a way to use this configuration without having to know preexisting passwords.

Repository structure

File/Directory	Explanation
flake.nix	Describes dependencies on other flakes ("inputs") and exposes structered configuration ("outputs"); this is essentially what makes this repository a "flake"
flake.lock	Lock file enforcing specific versions/commits of all flake inputs
lib/	Collection of nix functions interally used in this crate; exposed via the lib flake output
hosts/	Host-specific collections of nix files that get parsed into a single NixOS module per host by the customModule function in lib/customModule.nix
README.md	..self explanatory

Custom module structure

hosts/ contains top-level directories representing the different hosts this flake is designed to be used on.

Currently, hosts/laptop/ generates a NixOS module for the laptop nixosConfiguration and hosts/server/ generates a NixOS module for the server nixosConfiguration.

hosts/shared/ contains modules applying to both configurations, and is imported by both.

Each of these directories contains arbitrarily nested nix files where each nix file contains an attribute set with any of the following attributes:

Attribute	Explanation
system	If present, this attribute has to contain a valid NixOS module that will be incorporated into the system configuration. See here for reference and here for possible configuration values.
users	If present, this attribute has to contain an attribute set where each attribute name is equal to an existing user and the corresponding value has to contain a valid Home Manager module that will be incoporated into the user's Home Manager configuration. See here for reference and here for possible configuration values. Not every users set has to define modules for all existing users.
