I think the key overlooked fact is the possibility some application asks for a lot more /tmp space than is ever reserved for swap. Example: > > I'd expect Brisera to produce an ~9GB temp file when burning a fully consumed dual-layer DVD. Incorrect assumption? Minimum requirements for Fedora 16, 1152MB RAM. That translates into what default for swap space? Is this at least 4GB, or whatever the minimum amount of swap needed for tmpfs when full to overflow to? > > Does anyone know what the behavior of Scribus, GIMP, Cinelerra, etc. are when it comes to temp space requirements? I could see GIMP arbitrarily want multiple gigabytes of space, well beyond physical RAM plus that reserved for swap space. the developers of this "feature" try to explain us that applications should stop using /tmp and put their stuff in /var/tmp to make the "feature" possible as longer i think about the idea having /tmp in memory as default as lesser sense this idea is making for me however, as long my enry in /etc/fstab is honored all the users with default setups does not bother me, but that does not make things better for the overall quality of the distribution
