Description of problem:
Not able to create a mount point for a RAID1/LVM meta device

Version-Release number of selected component (if applicable):
DISK DRUID 

How reproducible:


Steps to Reproduce:
1. Needed 2 same-sized hard drives
2. Type "linux text" at the install-prompt
3. Create a meta device, choose:
FS=LVM
Raidlevel=1
4. Now create a mount point for the meta device, it is not possible because 
a "LVM-button" is missing.
    
Actual results:
Can't assign a mount point

Expected results:
Need a LVM-button to create a mount point

Additional info:
It is possible if you use the graphical install.
Is it possible to have the "LVM-button" in the text-install in the future. 
Thanks.
