However, I am not clear on how tmpfs will fail. If the tmpfs mount becomes filled or exceeds the file limit, since it is essentially just another disk partition shouldn't it produce a "No more space left on device" error? Or is the system designed to extend the tmpfs through swapping? The latter option doesn't seem right, but everyone still refers to such behavior. Frank Peters
