However, almost all distros now use persistant names for network devices due to the PCI Hotplug issue, so it isn't probably as bad as you might think. > Perhaps we need either a CONFIG option or a boot option to decide > whether to do parallel pci probes. Oh yeah, it will be probably both of them :) > I still think we need a method of renaming block devices, but haven't > looked into it in enough detail yet. That could get "interesting"... But now that we all are using /dev/disk/ and it has persistant device names for block devices, I really don't think it's that big of a deal. thanks, greg k-h
