### Why did you only define the root partition for these listed architectures?
|

|

The automatic discovery of the root partition is defined to operate on the disk
|
||||
containing the current EFI System Partition (ESP). Since EFI only exists on
|
||||
x86, x86-64, ia64, ARM and RISC-V so far, we only defined root partition UUIDs for
|

these architectures. Should EFI become more common on other architectures, we
|
||||
can define additional UUIDs for them.
