   7. mkswap /dev/mapper/data-swap
   8. mkfs.btrfs /dev/mapper/data-root
3. Create subvolumes.
   1. mount -t btrfs /dev/mapper/data-root -o noatime,ssd,space_cache=v2,commit=120,compress=zstd /mnt
   2. for i in root home nix persist log; do btrfs sub create /mnt/$i; done
   3. btrfs sub snap -r /mnt/root{,-blank}
   4. umount /mnt
   5. mount -t btrfs /dev/mapper/data-root -o noatime,ssd,space_cache=v2,commit=120,compress=zstd,subvol=root /mnt
   6. mkdir -p /mnt/{home,nix,persist,var/log,boot}
   7. for i in home nix persist; do mount -t btrfs /dev/mapper/data-root -o noatime,ssd,space_cache=v2,commit=120,compress=zstd,subvol=$i /mnt/$i; done
   8. mount -t btrfs /dev/mapper/data-root -o noatime,ssd,space_cache=v2,commit=120,compress=zstd,subvol=log /mnt/var/log
   9. mount /dev/BOOTPARTITION /mnt/boot
4. nixos-generate-config --root /mnt and copy relevant generated details to a new host under nixos/.
5. Write host-specific config under new host under nixos/.
   1. UUIDs can be found using blkid | grep UUID.

   1. mkdir -p /mnt/persist/passwd
   2. mkpasswd -m sha-512 > /mnt/persist/passwd/root
