33 * Don't start the slice at the default block of 34; many storage
34 * devices will use a stripe width of 128k, other vendors prefer a 1m
35 * alignment.  It is best to play it safe and ensure a 1m alignment
36 * given 512B blocks.  When the block size is larger by a power of 2
37 * we will still be 1m aligned.  Some devices are sensitive to the
38 * partition ending alignment as well.
