I dont think so, we either want to create the directory, or we want to mount it as a tmpfs (after creating the directory for a mount point of course). I think its probably best to leave it as a regular directory, rather than a tmpfs. The reason is because we already are providing a very minimal /tmp as a tmpfs, and this eats into the available memory on the entire box (this of course can be increased as needed, but it occupies memory space), adding a second tmpfs that must get mounted at /dev/shm will further complicate this resource problem. I think that the best way to handle it is to leave it as a directory, and let the admin decide if they want to remount it as a tmpfs for optimization purposes and based on their particular host's memory availability.
