* Partition Scheme

| Position | Label          | FS Type | Size  | Type                 |
|----------+----------------+---------+-------+----------------------|
|        0 | =Infini-STICK= | =btrfs= | 29.3G | Root Partition       |
|        1 | =boot=         | =vfat=  | 511M  | EFI System Partition |

* Configuration

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