[REQUEST] Add a way to create partitions

[ad2017]

Hey, I wanted to test my OS on a virtual machine (not debugging), but I didn't know that COSMOS isn't able to create partitions. It would be really useful if it could, as you could install it on a brand new drive.

I really hope this will become a thing. Thanks.

Its just a matter of time. So much to do, so few developers...
