```bash
# format the boot partition
mkfs.fat -F 32 /dev/sda1 -n "nixboot"
# create an encrypted partition
cryptsetup luksFormat -y --label="nixcrypt" /dev/sda2
# open the encrypted partition and map it to /dev/mapper/cryptroot
cryptsetup luksOpen /dev/sda2 cryptroot

# create the physical volume
pvcreate /dev/mapper/cryptroot
# create a volume group inside
vgcreate lvmroot /dev/mapper/cryptroot
# create the swap volume
lvcreate --size 8G lvmroot --name nwap
# if you desire, create a home volume
lvcreate --size 150G lvmroot --name home
# create the root volume
lvcreate -l 100%FREE lvmroot --name root

# format as usual for root partition
mkfs.ext4 -L "nixroot" /dev/mapper/lvmroot-root
# if you previously made the home partition, do it too
mkfs.ext4 -L "nixhome" /dev/mapper/lvmroot-home
# format the swap partition
mkswap -L "nixswap" /dev/mapper/lvmroot-swap

# mount root
mount /dev/disk/by-label/nixroot /mnt
# mount boot
mount --mkdir /dev/sda1 /mnt/boot
# again, if you did the home volume
mount --mkdir /dev/disk/by-label/nixhome /mnt/home
# turn on swap
swapon /dev/disk/by-label/nixswap
