sudo parted /dev/disk/by-id/example -- mkpart pv-enc 512MiB 100%
sudo parted /dev/disk/by-id/example -- mkpart ESP fat32 1MiB 512MiB
sudo parted /dev/disk/by-id/example -- set 2 esp on

# Encryption
sudo cryptsetup luksFormat /dev/disk/by-partlabel/pv-enc
sudo cryptsetup luksOpen /dev/disk/by-partlabel/pv-enc pv

# Logical volumes
sudo pvcreate /dev/mapper/pv

sudo lvcreate --name swap --size 4G vg
sudo lvcreate --name root --extents '100%FREE' vg

# Filesystems
sudo mkfs.fat -F 32 -n boot /dev/disk/by-partlabel/ESP
sudo mkswap --label swap /dev/vg/swap
sudo mkfs.btrfs --label root /dev/vg/root

# Manual mounts
sudo swapon /dev/disk/by-label/swap
sudo mount -t btrfs -o compress=zstd,noatime /dev/disk/by-label/root /mnt
