What does that mean? "auto-generate"? By whom?
The admin tells the kernel module to auto-generate a WWN, and the kernel
module happily obliges.
The generation algorithm is whatever makes people happy. I would
probably pick a fixed prefix like 0x6C 0x69 0x63 ("lin"), something that
doesn't conflict with IEEE org ids for a long time to come. Then,
get_random_bytes() or hash some useful machine characteristics for the
rest of the bytes.
What if they don't "auto-generate" (whatever that means)?
Well, you either have a WWN or you don't :)
