## Installing
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.
