The function is indeed creating a mounpoint not a Volume; the
latter is not even well defined in our "ontology".

b0899c5c59 disk: new interface UniqueEntity for Entities with UUID
This is for all entities that have a uniquely identifiable via a UUID.
Currently the interface only contains a single function, GenUUID(),
that should generate a new UUID via a random source (`rand.Rand`).
NB: Partitions are uniquely identifiable if and only if the layout is
GPT.

221cdedebc disk: Entity types must implement Clone()
All disk.Entitity types now implement Clone() which should return a
deep copy of the same object. Add the Clone() method to the entity
interface. The return type is Entity, but callers can assume it's
safe to convert back to the original type.
