After Kickstart installation of Red Hat Enterprise Linux 6.4 beta, the logical volume names are not set as per mentioned in kickstart file

Issue

• Installed Red Hat Enterprise Linux 6.4 Beta with the help of a kickstart file
• The installation went fine but the logical volume names are updating as expected.
• The kickstart file contains the following logical volume names

clearpart --all --initlabel
part /boot --fstype ext3 --size=100 --asprimary
part pv.01 --size=4000 --grow --asprimary
volgroup vg00 pv.01
logvol swap  --vgname=vg00 --name=lv_swap   --size=1000
logvol /     --vgname=vg00 --name=lv_root   --fstype ext3  --size=3000
logvol /tmp  --vgname=vg00 --name=lv_tmp    --fstype ext3  --size=100
logvol /var  --vgname=vg00 --name=lv_var    --fstype ext3  --size=2000

But the logical volume names are set as v_swap,v_root,v_tmp and v_var instead of lv_swap,lv_root,lv_tmp and lv_var
