Well, most systems clean up /tmp on boot, so they discard the content as well. > the shm_open impl on linux does ensure reboots == doesn't survive. That's not true. The shm_open implementation on Linux just ensures that it is using /dev/shm if available (or whatever they moved it to nowadays). It is up to the distribution to mount a tmpfs to that. Syncing to disk is often a *good* thing as it tends to significantly reduce the memory pressure *and* tends to provide more efficient reload behavior than swap. So yes, shm_open is pretty lame.
