Partitioner does not specify sunit/swidth for XFS+dmcrypt+RAID

[xor]

- Do a Netboot install using PXE, Ubuntu 12.04 image obtained from http://archive.ubuntu.com/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/netboot.tar.gz
- Select "Partition disks - manual"
- Create a RAID5, dm-crypt with passphrase on top of it, and XFS as root filesystem on top of the dm-crypt.
- Finish installation
- Execute "xfs_info /". You will see that sunit and swidth are both not specified. They should be specified for XFS on RAID to improve performance.
