Partitioning

Yes. Both the gdisk recommended there and the new fdisk mentioned by rh-kzak align partitions to 1 MB, which is much better than what the old fdisk does in many current distros.

However, the alignment should really be 4 MB or higher, not 1 MB, at least on the low-end devices. I hope to get optimizations for 4 MB segments into btrfs, ext4 and other file systems, but they can only work if the file system is fully aligned.
