That's true, but not the point. When the YaSt Partitioner is started, it calls: /usr/sbin/parted -s /dev/sda unit cyl print unit s print When I then create a partition of 100 MiB, it issues: /usr/sbin/parted -s --align=optimal /dev/sda unit cyl mkpart primary ext2 1569 1582 The desired result would be achieved instead with: /usr/sbin/parted -s --align=optimal /dev/sda unit MiB mkpart primary ext2 12300 12400 I understand that the YaST partitioner works as designed, but it sticks to a convention which does not make much sense on newer systems. Please consider this bug report therefore as an improvement proposal for future versions.
