+=item $partitions = $h->sfdisk_disk_geometry ($device);
+
+This displays the disk geometry of C<device> read from the
+partition table. Especially in the case where the underlying
+block device has been resized, this can be different from the
+kernel's idea of the geometry (see C<$h-E<gt>sfdisk_kernel_geometry>).
+
+The result is in human-readable format, and not designed to
+be parsed.

+=item $partitions = $h->sfdisk_kernel_geometry ($device);
+
+This displays the kernel's idea of the geometry of C<device>.
+
+The result is in human-readable format, and not designed to

+
+=item $partitions = $h->sfdisk_l ($device);
+
+This displays the partition table on C<device>, in the
+human-readable output of the L<sfdisk(8)> command. It is
+not intended to be parsed.
