Anaconda issues with LVM when using an entire disk as a LVM physical partition

[Adam Gibson]

I created a second disk /dev/hdb as an LVM partition manually in FC4. 
There are no partitions like /dev/hdb0, etc.  /dev/hdb is the partition.

When Anaconda first starts up it says that the disk is not initialized 
and asks if you want to initialize it(which would have hosed my LVM on 
that disk).

As long as you answer no to the initialization when you get to disk 
druid, it does show the LVM partition but you can not do anything with it.

I am ok that it can not edit it because it does not expect the entire 
disk to be a partition, but the scary part was when it said the disk was 
uninitialized and asked to initialize it.  Someone might accidentally 
say yes to that not realizing that it is already initialized in a sense 
that the entire disk is an LVM partition.
