I am doing kickstart installs for many years now. But out of the sudden, Anaconda started to create a partition for those disks I am putting under LVM. Is this intentional or a implemented bug?
Even though I have this in my kickstart file (example):

OS:

part pv.02 --fstype="lvmpv" --ondisk=sdc --size=16383 --grow
volgroup vgos --pesize=4096 pv.02
logvol / --fstype=ext4 --vgname=vgos --size=256 --name=root
logvol /usr --fstype=ext4 --vgname=vgos --size=3072 --name=usr

It still creates a partition:

sdc 8:32 0 16G 0 disk
└─sdc1 8:33 0 16G 0 part
├─vgos-root 253:0 0 256M 0 lvm /
├─vgos-usr 253:2 0 3G 0 lvm /usr

My intention is to put the entire disk under the control of LVM.
