Subject: [PATCH] nvme: Require additional rpms for dracut
The '95nvmf' dracut module needs a couple more packages
for the NBFT (NVMe over TCP) to work - such as networking.
Local PCIe NVMe devices have no special needs.

Subject: [PATCH] Do not add new PVs to the LVM devices file if it doesn't
exist and VGs are present
If there is a preexisting VG on the system when we create a new PV
and the LVM devices file doesn't exist we will create it and add
only the new PV to it which means the preexisting VG will now be
ignored by LVM tools. This change skips adding newly created PVs
to the devices file in the same way 'pvcreate' and 'vgcreate' do.
