Description of Problem: Partition command in 7.2 Kickstart file appears to need --size to specify minimum size if --grow option is used. 7.1 did not. Version-Release number of selected component (if applicable): Works in 7.1, not in 7.2 How Reproducible: Appears to be easy to reproduce. Unclear whether this is actually a bug, but I thought that I ought to bring it to your attention.
7.1 did this as well (I've closed a few bugs where people haven't had a size specified). Otherwise, there's no real way to tell how to relatively grow partitions if more than one partition is specified with --grow.
