And when you ask that single "fake" partition for it's device
name, will it be "/dev/sda" or "/dev/sda1"? Any answer is looking
for trouble, e.g. with "/dev/sda" you have several objects with
the same device name (have fun finding the right one), with
"/dev/sda1" you cannot e.g. use the device name to mount the

Well, if idea is that disk act as partition, then for me naive answer
is /dev/sda as /dev/sda is disk and also partition with file system. So
