1. IDE only, scsi-disk is missing.
Correct.
IDE support is easy.

Adding SCSI support is more complicated, because "model" and "serial"
are not the only factors that can make up a  /dev/disk/by-id link
Could be a combination of 3 fields: vendor, model and serial.
But could also be based on another unique ascii or binary identifier
provided by the drive through Vital Product Data page 83h.
I am going to add customization of VPD page 83h soonish (though only
limited to another ASCII identifier), and Dmitry Fleytman told me
offlist that he's going to add vendor/model support too.

Nice

That said, I agree with the other comments from Markus.

Fair enough.
You guys outnumber me, so I will resubmit my IDE patch without the legacy -drive support.


Yours sincerely,

Floris Bos
