Solaris traditionally uses cylinders for fdisk partitions and slices. When you convert from cylinders to MB/GB and back, there were some rounding off errors. That caused issues with other partition tools. So we use sectors as our basic size. If some one wants to create partitions with out gaps, they could specify sizes in sectors.
