Programs that use explicit major/minor information are probably broken or at least very nonportable. On the other hand, unfortunately the Unix API has a few explicit occurrences of major/minor. For example, one has ls(1) and mknod(1). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
