How do I create a true RAM disk? I don't want a virtual file system with loop devices, I would like a mountable filesystem that is stored completely in RAM.
I am using Fedora 17, linux 3.6.9-2.fc17.i686
Thanks in advance.
See the man page for more details.
It limits to 50% of your total RAM available by default (configurable - see 'Mount options for tmpfs' in the manpage
