[Bug 1826737] Re: lshw does not list NVMe storage devices as "disk" nodes ( RedHat Bug 1695343 )

[Stephen Boston]

@Yuan - Thank you.

For precedent in this issue can we look to the transition from tape to
disk? Both are devices for persistent storage but each is in its own
class. Now with NVM we have a third type of storage device so perhaps we
should consider a new class.

lshw is a hardware listing. Classifying NVM as 'disk' is a metaphor. So
the question is how far are we comfortable introducing or extending
metaphor into a hardware listing? Can we live with that loss of
precision?
