Why do they need to be cleaned up on reboot? The problem with sharing files between applications using /tmp is this specification: http://www.pathname.com/fhs/pub/fhs-2.3.html#TMPTEMPORARYFILES | Programs must not assume that any files or directories in /tmp are | preserved between invocations of the program. So in case there will be a file system for /tmp that automatically removes files once they are not open anymore, abusing /tmp for this will fail. Regards Till
