Yes, could be done that way, but I want to retain compatibility with existing shell scripts doing things like:
DEVICE=/dev/megaraid_sas_ioctl_node DEVICENAME=megaraid_sas_ioctl DEVICEPERM=400 MAJOR=`grep "$DEVICENAME" /proc/devices | awk '{print $1}'`
if [ -n "$MAJOR" -a ! -e "$DEVICE" ]; then mknod "$DEVICE" c "$MAJOR" 0 chmod "$DEVICEPERM" "$DEVICE" fi
