Ceph only cares about the SSD and HDD distinction right now, so that's all the device classes try to handle. (In fact it's *actually* just looking at the rotational flag the kernel exports; the detection would need to become a lot more advanced to start assigning stuff to an nvme class.)

Hello,
It looks like Ceph (13.2.2) assigns device class "ssd" to our Samsung
PM1725a NVMe SSDs instead of "nvme". Is that a bug or is the "nvme"
class reserved for a different kind of device?
