* Fix partition alignment and image rounding when any of -P (block size),marcel2014-09-191-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | -T (track size) or -H (number of heads) is given: o scheme_metadata() always rounded to the block size. This is not always valid (e.g. vtoc8 that must have partitions start at cylinder boundaries). o The bsd and vtoc8 schemes "resized" the image to make it match the geometry, but since the geometry is an approximation and the size of the image computed from cylinders * heads * sectors is always smaller than the original image size, the partition information ran out of bounds. The fix is to have scheme_metadata() simply pass it's arguments to the per-scheme metadata callback, so that schemes not only know where the metadata is to go, but also what the current block address is. It's now up to the per-scheme callback to reserve room for metadata and to make sure alignment and rounding is applied. The BSD scheme now has the most elaborate alignment and rounding. Just to make the point: partitions are aligned on block boundaries, but the image is rounded to the next cyclinder boundary. vtoc8 now properly has all partitions aligned (and rounded) to the cyclinder boundary.
