## Prepare partitions

fdisk -l

$ gdisk /dev/sda
n       # new partition
<enter> # default partition #
<enter> # default start location
+512M   # size 512MB
ef00    # type boot

n       # new partition
<enter> # default partition #
<enter> # default start location
<enter> # size remaining space
<enter> # type default

w       # write partitions
y       # confirm

## Configure Encryption

root_partition=/dev/sda$PARTITION_NUMBER # e.g., /dev/sda5

cryptsetup luksFormat $root_partition
cryptsetup open --type luks $root_partition enc-pv
pvcreate /dev/mapper/enc-pv
vgcreate vg /dev/mapper/enc-pv
lvcreate -L 10G -n swap vg
lvcreate -l 100%VG -n root vg

## Format partitions

boot_partition=/dev/sda$PARTITION_NUMBER # e.g., /dev/sda4

mkfs.vfat $boot_partition
mkfs.ext4 -j -L root /dev/vg/root
mkswap -L swap /dev/vg/swap


## Mount partitions

mount /dev/vg/root /mnt
mkdir /mnt/boot
mount $boot_partition /mnt/boot
swapon /dev/vg/swap

# Revert (this not necceseary just in case you wan't revert back here)

cryptsetup open --type luks $root_partition
lvchange -ay vg

## Configure

nixos-generate-config --root /mnt

## Install

nixos-install
