# Set variables
```sh

```
# Partition disk
```sh
parted -s "$disk" mklabel gpt
```
## boot
### MBR
We don't do MBR anymore!
### EFI
```sh
parted -a optimal "$disk" mkpart primary fat32 1MiB 1001MiB
parted "$disk" set 1 esp on
mkfs.vfat -F32 "${disk}1"
```
## swap
```sh
swap_end=$(awk '/MemTotal/ { print int($2 / 1000 * '"$swap_ratio"') + 1001 }' /proc/meminfo)
parted -a optimal "$disk" mkpart primary linux-swap 1001MiB "$swap_end"
mkswap "${disk}2"
swapon "${disk}2"
```
## zpool
```sh
parted -a optimal "$disk" mkpart primary "$swap_end" 100%
zpool create \
-O mountpoint=none \
-O encryption=on \
-O keyformat=passphrase \
-O keylocation=prompt \

### zfs volumes
```sh

zfs create -o mountpoint=legacy "$zfs_pool/rootfs/nixos"
zfs create -o mountpoint=legacy "$zfs_pool/homefs"

zfs create -o mountpoint=legacy "$zfs_pool/homefs/tyil"
```
# Mount partitions/volumes
```sh
mount -t zfs "$zfs_pool/rootfs/nixos" /mnt
mkdir -pv -- /mnt/boot
mount -t vfat "${disk}1" /mnt/boot
mkdir -pv -- /mnt/home
mount -t zfs "$zfs_pool/homefs" /mnt/home
mkdir -pv -- /mnt/root
mkdir -pv -- /mnt/home/tyil
mount -t zfs "$zfs_pool/homefs/root" /mnt/root
mount -t zfs "$zfs_pool/homefs/tyil" /mnt/home/tyil
```
# Install NixOS
## Configure
```sh
nixos-generate-config --root /mnt
```
Apply configs in `/mnt/etc/nixos`
```nix
{
boot.supportedFilesystems = [ "zfs" ];
boot.zfs.devNodes = ...
boot.zfs.forceImportRoot = false;
networking.hostId = $(head -c4 /dev/urandom | od -A none -t x4)
networking.hostName = ...
}
```
## Install
```sh
cd /mnt && nixos-install
```
## Reboot
```sh
umount -lR /mnt
zpool export "$zfs_pool"
```
