|----------+----------------+-------------+--------+-----------------------------|
|        0 | =storage=      | =exfat=     | 24.6GB | Generic Storage Partition   |
|        1 | =vault=        | =LUKS/ext4= | 3GB    | Encrypted Storage Partition |
|        2 | =Infini-STICK= | =btrfs=     | 33.3GB | Root Partition              |
|        3 | =boot=         | =vfat=      | 511MB  | EFI System Partition        |

* Configuration

Setup with a wide array of hardware compatibility, specifically using the =portable= form defined in the =hardware/form= module.

=Infini-STICK= currently lives on my SanDisk 3.2Gen1 64GB USB C/USB A flashdrive.
