A ramdisk is a block device which exists in RAM and is (usually) static 
in size, whereas a tmpfs exists in virtual memory ─ which means that its 
contents can be paged out to disk ─ and only consumes as much virtual 
memory as per the value of whatever is stored on it.  

If you create a tmpfs with nothing on it, then it won't consume any 
virtual memory (apart from an inode for its root directory).
