Linux 2.6 udev capability question
Quoted 9 lines · Jonathan A. George
Greg & Al,
Will the udev model somehow support the ability to associate a device node with a specific device?
For example in a Fibre Channel, SCSI, iSCSI (SAN) date network environment it would be nice to associate a specific device driver handle per (WorldWideName and/or Type+Vendor+Model+Serial#).

It would also be nice to be able to associate via the LUN target path.
Obviously the same basic problem space applies to USB devices, and I have admittedly not reviewed the specs for sysfs and udev in 2.6. If the answer to all of these questions is Yes+RTFM that would make me very happy. Otherwise I would be interested in knowing whether or not it is even possible in the udev model, and if it is what would be the recommended approach to implementation.
Yes, RTFM :)

P.S. Feel free to forward your response to LKML since there are no doubt others with the same question in mind.
Will do. Why did you not ask this there in the first place? Sending email directly to developers isn't the nicest thing to do:

Thanks for your response.
As you sent this to me privately, I take it you didn't read the above link?

Is there an official udev web page or forum?
No, nothing is ever "official" :)
The linux-hotplug-devel mailing list has been a good place to discuss udev stuff.

As to why not use mailing list in the first place: A. Who wants to get flamed by Al in public. ;-) B. Giving consideration to the developer who might want to discuss the issue before exposing it to a public forum. I probably have sent about 50 emails to the LKML over the last eight years on topics from VMM to SCSI to SCM, but sometimes it seems better to directly address the relevant developer. Not everyone subscribes to the list after all. ;-)
But it saves developer time, which is in much shorter supply than "users who don't read the documentation time" it seems...

Russell's site was not working when I received your initial response. It is now. As I mentioned if you search the LKML archives you will find that I normally do use the list first unless I know that someone isn't subscribed.
