No one disputes that cdrecord's (bus,target,lun) triples can be used to uniquely identify a particular device on the system at a particular time.

What they do argue is that it is pointless to use the triples for device identification, since you can achieve the same identification by using the device files.

Secondly, given that we use device files to identify the device with mount, cdparanoia and almost every other tool, using (bus,target,lun) triples for writing CDs is inconsistent.

'The same' identification? I have one CD-ROM drive and two CD burners of the same make on my machine. cdrecord -scanbus is useless: which burner is which? It can't tell me.

But udev knows: /dev/burners/lower and /dev/burners/upper are quite unambiguous.

I find it pretty asinine that I have to figure out the mapping between one namespace and the other just to get cdrecord to notice my drive. I don't know how many times I screamed in frustration trying to figure out exactly which incantation and which combination of ide vs. ide-scsi would make my drives visible to cdrecord, even when they were visible to everything else, including cdparanoia.
