lvm, creation of physical volumes

[Jan Michael]

Hi Greg, hi Steve, hi list,

I'm sorry. It seems to be that I put concern in wrong words.
I don't want anaconda/kickstart to set up the whole lvm environment  
for the system.
Anaconda should simply create the partition and initialize this  
partition to make it ready for lvm usage.

The reason why it is not necessary to create a volume group is, that  
this will be done by another component later in the installation  
process.

I would like to know, if the part command takes care of the creation  
of the partition and its initialization (i.e. with pvcreate) or if it  
is not possible to seperate this step from the volume group creation.

Cheers,

	Jan
