NOTES
If mknod(2) is used to create a device, the major and minor device numbers are always interpreted by the kernel running on that machine.
With the advent of physical device naming, it would be preferable to create a symbolic link to the physical name of the device (in the
/devices subtree) rather than using mknod.
