Hi John,

What is your need for a RAM disk?  With the advent of solid
state drives (SSD) access to files is much faster, so there
is less need for RAM disk. Also, I believe linux will cache
disk files in RAM. 

I recall hearing linux behaves better with a swap file, even if it is 
used very little.
