What's wrong with the current sysfs way of adding new device ids without

added that functionality, so users would not have to constantly update
their kernel. The distros provide userspace tools that enable these ids
to be added and at boot time, everything "just works" properly.
I haven't found a single distro that (a) makes it trivial to add PCI IDs at
install time, and then (b) ensures those PCI IDs remain persistent for each
boot. We are not at all to the "just works" stage yet.
Well, SuSE handles this just fine, but I do notice that RHEL 5 disables
the new_id stuff entirely, so I can see why you might get this
impression :)
That's news to me. I didn't even realise it was possible to disable this.
Pointer?
I'm just trying to point out that the new_id sysfs stuff is there
explicitly for this very reason, as people were demanding that (Dell
being the major company behind it.)
Theres more to this than just PCI IDs though.
ac97 ID updates, usb id updates, etc, etc.
We have many different forms of what are fundamentally, the same thing.
