## Installing
### NixOS
This configuration uses impermanence with btrfs snapshots so you'll have to partition
your system in a certain way.
First you'll need this partition layout, assuming you're installing on `nvme0n1`.
```
DEVICE FILESYSTEM PURPOSE
/dev/nvme0n1
├─/dev/nvme0n1p1 vfat EFI partition
└─/dev/nvme0n1p2 btrfs Partition to house all the subvolumes
```
Inside of the btrfs root volume we're going to need 2 subvolumes.
```
SUBVOLUME MOUNT PURPOSE
root / Impermanent data
nix /nix Permanent data
```
You'll also need to create a read-only snapshot of the `root` subvolume
and call it `root-blank`.
After you've mounted all the subvolumes and EFI partition (`/boot`) in `/mnt`
clone this repository in to `/mnt/nix/config`. Adjust all the block ids of the partitions
in `hardware-configuration.nix` and create a hashed password using `mkpasswd` and store it
in the `secrets/{user}` directory as `pass`.
Finally, in the config directory run `nixos-install --flake '.#'`, reboot and you're done.
### Non-NixOS
Run the `non-nixos-install.sh` script. It will install both home-manager and nix.
Your user is assumed to be called "i". You need to replace every instance of it
in case you want to use a different username.
