If you are using the Linux ABI then you'll hit cases (in particular tty cases) where the ABI/API knows about major/minor numbers. In addition the standards and common sense together pretty much imply that you need each device to at least have a unique identifier. Finally you need major/minor numbers to NFS serve to a diskless client. Most Linux device numbering beyond that is basically dynamic so it probably does't matter that much for things you concoct - providing in som cases your /proc table of major numbers is right. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
