[ILUG] firewall

[Philip Creevy]

The general concensus is that 4GB is to big and 512MB would be loads.
This box would be headless so no GUI would be needed.
I was not planning on running squid on this box.

>From the research I did on the MUVO it does use 
flash and this is causing the supplier a problem
as people are breaking them to get the cheap memory.

If all logs are lost on power down does this cause any
problems on the next startup.

I assume RAM disk, RAM drive are the same thing they 
both use ram to create a virtual drive ???
