Comment 4 for bug 1987236

Hi Dan, yes, that's what I think.
On the wast majority of s390x systems there are so called "ccw" (zSystems specific) devices, and we definitely need to find them and offer to configure them.
But on some installations that might not be the case, but this should not break or stop the installation, since it can be a system without any ccw devices, like just zPCI based devices (NVMe for disk and Mellanox for networking).
So I think the case where chzdev fails (btw. maybe also 'lszdev' is somewhere used in the code) because no ccw devices are there, just need to be properly caught, and the installation should proceed..

The workaround /kind of/ proves that already (creating a virtual so called hipersocket 'ccw') networking device that is not used at all and just sits there to make chzdev happy.
