nixos-config

This repository gathers all the configuration needed to install NixOS on several machines using flakes. It is a work in progress. I'm really new at NixOS and I want to experiment and learn about it step by step.

Installation

• Boot the system using NixOS live USB

• Execute the installation script which is located in scripts/install.sh

  curl -sL https://raw.githubusercontent.com/egara/nixos-config/main/scripts/install.sh | bash -s <hostname> <username>
  

Please, change hostname and username by one of their accepted values:

• hostname: vm
• username: egarcia

This script will:

1. Clone this repository https://github.com/egara/nixos-config.git
2. Format and create all the needed partitions using Disko
3. Install NixOS
4. Copy this repo into the new installed system

Partitioning

This stage will be created automatically by Disko.

VM

This is the selected layout for the UEFI/GPT system:

Mount point	Partition	Partition type	FS Type	Label	Bootable flag	Size
/boot/efi	/dev/vda1	EFI System Partition	FAT32	UEFI	Yes	512 MiB
[SWAP]	/dev/vda2	Linux swap	SWAP	swap	No	1 GiB
/	/dev/vda3	Linux	BTRFS	system	No	Available

BTRFS Layout

This is the layout defined:

(Volume)
|
├─ @ (Subvolume - It will be the current /)
|
├─ @home (Subvolume -  It will be the current /home)
|
├─ @snapshots (Subvolume -  It will contain all the snapshots which are subvolumes too)

The whole volume will be mounted and available at /mnt/defvol once the system is installed.
