I don't think it needs to be a class, but I think that there should be a
single place with a directory for each device that could be what you want,
with a file that tells you if it is. That's why I was looking at block/;
these things must be block devices, and there aren't an huge number of
block devices.
I suppose "grep 1 /sys/block/*/device/dvdwriter" is just as good; I hadn't
dug far enough in to realize that the reason I wasn't seeing anything
informative in /sys/block/*/device/ was that I didn't have any devices
with informative drivers, not that it was actually supposed to only have
links to other things.
It would be nice to have one place to go to find burners, and to have
the model information in that place. I would logically think that place
is sysfs, and I know the kernel has the information because if I root
through /proc/bus/usb and /proc/scsi/scsi, and /proc/ide/hd?/model I can
eventually find out what the system has connected.
I not entirely sure about having classes other than cdrom, just because
we already have CD, DVD, DVD-DL, and are about to add blue-ray and
HD-DVD, so if I can tell that it's a removable device which can read
CDs, the applications have a fighting chance to looking at the device to
see what it is. As a human I would like the model information because
the kernel has done the work, why should people have to chase it when it
could be in one place?
