Description of problem:
To setup a couple of desktop clients with different harddisks (different in size) it is necessary to create a partition table within the kickstart which consists of a boot partition and a raid1. The raid partition on each disk should grow to the maximum available space of the disk. On the raid1 an lvm volume will be created

Version-Release number of selected component (if applicable):
anaconda as shipped with install media

How reproducible:
Add a raid partition with --grow as option.


Steps to Reproduce:
1. create a kickstart with raid partitions and use --grow as in advanced partitioning example of the documentation
2. start kickstarting you computer with kickstart file created and kickstart will fail

  
Actual results:
Kickstart stopps with an error message that --grow is not supported with raid partitions


Expected results:
--grow should work with raid partitions again. In Fedora 13 it works and I think there's no reason to leave this out for raid partitions.


Additional info:
Without this feature Fedora is no longer useful for setting up a lot of desktops with harddisks of different size. 

There's similar bug reported that documentation is not correct. But the main goal is to get --grow working again together with raid partitions.
