Partition layout

Partition	Type	Size
p1	boot	512 MiB
p2	SWAP	16 GiB
p3	btrfs	-

Create encrypted partition and btrfs subvolumes

export DISK=/dev/nvme0n1

cryptsetup --verify-passphrase -v luksFormat "$DISK"p3
cryptsetup open "$DISK"p3 enc

mkfs.vfat -n boot "$DISK"p1
mkswap "$DISK"p2
swapon "$DISK"p2
mkfs.btrfs /dev/mapper/enc

mount -t btrfs /dev/mapper/enc /mnt

btrfs subvolume create /mnt/home
btrfs subvolume create /mnt/nix
btrfs subvolume create /mnt/persist

umount /mnt

Mount tmpfs, partitions and subvolumes and generate config

---

FIXME: Mounting a ramdisk as root may be a bad idea for installation since building the config needs a lot of disk space. Consider mounting some temporary folder and deleting it afterwards or giving the tmpfs more ram.

---

mount -t tmpfs none /mnt

mkdir -p /mnt/{boot,home,nix,persist}
mount "$DISK"p1 /mnt/boot
mount -o subvol=home,compress=zstd,noatime /dev/mapper/enc /mnt/home
mount -o subvol=nix,compress=zstd,noatime /dev/mapper/enc /mnt/nix
mount -o subvol=persist,compress=zstd,noatime /dev/mapper/enc /mnt/persist

nixos-generate-config --root /mnt

Compare the generated hardware-configuration.nix with machines/aztec/hardware-configuration.nix, adjust and push to GitHub if needed.
