Root partition size. Note that this option will either create just a root partition "/" and place the home directory on it, or create a root partition "/" and a home partition "/home" and will split the available space between them. This difference is triggered by the size of available space: if the space is under or equal to 50GB, then there's just a root partition "/" and /home is placed on it. For anything over 50GB, 50GB is allocated to the root partition and the rest is allocated to the "/home" partition.
