[rhelv6-beta-list] How can I align the boundary of partition / LVM / FS within the kickstart script?

How can I align the boundary of partition / LVM / FS within the kickstart
script?

There are 3 case which we need align with:

1.	The new 4k sector-size hard disk.
2.	The strip size of a RAID array.
3.	The block size of SSD erasing.

But the anaconda always align partitions with 63.5kib, and set the size of
LVM header to 192kib.
How can I do something to adjust it?
