Description of problem:

I tried to install F12 beta onto a disk, that does NOT have 
a partition table. It rather has only LVM2 on it:

file -s -k /dev/sdb
/dev/sdb: LVM2 (Linux Logical Volume Manager) , UUID: ...

While the F12-beta-KDE-Live-CD does not have any problems with
this particular disk - it does recognize the logical volumes on it -,
the installer refuses to accept this disk as installation target.

It offers only two options to me: 
1. Initialize the disk (a vague term, but most probably not what I want)
2. Ignore the disk (not either, what I want).


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

Fedora 12 Beta on x86-64



How reproducible:

Always.


Steps to Reproduce:
1. Boot the installation DVD
2. Click through all the questions...
3. ... up to the point, when it comes to the gparted section.


  
Actual results:

In gparted /dev/sdb does NOT show up, when I have chosen "ignore...".
Not a surprise, but not what I want.


Expected results:

I would have wanted the installer to accept this disk without writing any partition table to it, and to recognize the logical volumes that were already
present on this disk.  Actually, I do not want
gparted to write anything to this disk. Except for creating
/etc/fstab, maybe, i.e. defining the mount points. But not anything 
to any first sector of any disk.
