# Nix
|
|
|
|
My grand, declarative, and unified application, service, environment, and
|
|
machine configuration, secret, and package management in a single flake. ❤️ ❄️
|
|
|
|
**NOTE**: Everything in here is highly specific to my personal preference. I
|
|
can't recommend you actually use this in any way, but hopefully some stuff in
|
|
here is useful inspiration.
|
|
|
|
# Quick Start
|
|
|
|
You don't have even have to clone this crap yourself. How cool is that!
|
|
|
|
But if you're gonna change stuff you had better setup the pre-commit hook:
|
|
|
|
```shell_session
|
|
ln -s $PWD/pre-commit.bash .git/hooks/pre-commit
|
|
```
|
|
|
|
## NixOS
|
|
|
|
```shell_session
|
|
nixos-rebuild --flake git+https://git.lyte.dev/lytedev/nix switch
|
|
```
|
|
|
|
## Not NixOS
|
|
|
|
```shell_session
|
|
$ curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install
|
|
$ nix profile install github:nix-community/home-manager
|
|
$ home-manager switch --flake git+https://git.lyte.dev/lytedev/nix
|
|
```
|
|
|
|
# Advanced Usage
|
|
|
|
## Push NixOS Config
|
|
|
|
```bash
|
|
nix run nixpkgs#nixos-rebuild -- --flake 'git+https://git.lyte.dev/lytedev/nix#host' \
|
|
--target-host root@host --build-host root@host \
|
|
switch --show-trace
|
|
```
|
|
|
|
<!-- TODO: how to do this with rollbacks if I don't confirm things? -->
|
|
|
|
## Provisioning New NixOS Hosts
|
|
|
|
```bash
|
|
# establish network access
|
|
# plug in ethernet or do the wpa_cli song and dance for wifi
|
|
wpa_cli scan
|
|
wpa_cli scan_results
|
|
wpa_cli add_network 0
|
|
wpa_cli set_network 0 ssid "MY_SSID"
|
|
wpa_cli set_network 0 psk "MY_WIFI_PASSWORD"
|
|
wpa_cli enable_network 0
|
|
wpa_cli save_config
|
|
|
|
# partition disks
|
|
nix-shell --packages git --run "sudo nix run \
|
|
--extra-experimental-features nix-command \
|
|
--extra-experimental-features flakes \
|
|
github:nix-community/disko -- \
|
|
--flake 'git+https://git.lyte.dev/lytedev/nix#${PARTITION_SCHEME}' \
|
|
--mode disko \
|
|
--arg disks '[ \"/dev/${DISK}\" ]'"
|
|
|
|
# install
|
|
nix-shell --packages git \
|
|
--run "sudo nixos-install \
|
|
--flake 'git+https://git.lyte.dev/lytedev/nix#${FLAKE_ATTR}' \
|
|
--option substituters 'https://nix.h.lyte.dev' \
|
|
--option trusted-public-keys 'h.lyte.dev:HeVWtne31ZG8iMf+c15VY3/Mky/4ufXlfTpT8+4Xbs0='"
|
|
```

# To Do
|
|
|
|
- Port configuration (lytedev/dotfiles) to home manager where applicable?
|
|
- Sway, Kitty, and Helix, come to mind
|
|
- Installation from a live ISO does not fully work yet
|
|
- I don't understand Nix well enough to know why stuff is being compiled even when I have a binary cache
|
|
- Maybe it detects different CPUs and will recompile certain packages for per-CPU optimizations?
|
|
- How does this factor in with "pureness"?
|
|
- Custom pre-configured live ISO
|
|
- Unify standalone home manager module with NixOS home manager module
|
|
- Pre-commit checks with stuff like `nix flake check` and formatting checkers
