f15 install ssd alignment

[Neal Becker]

I'm about to try install f15 to a fresh SSD.  How can I make sure anaconda will 
align partitions properly?
Would it be better to avoid LVM to achieve this?

(sounds like lvm is not going to be easy, according to this:

I'm going to try anaconda, not messing directly with low-level tools
)
