   tmpfs does by default reserve half of your RAM - although it will   
   actually only use as much as is required - unless you specify otherwise   
   in the mount options.   
      
   There is no default configuration file for it, except maybe /etc/fstab,   
   if the tmpfs is mounted via that.  Many of the things like /dev/shm or   
   /run /may/ however already be mounted by the init scripts - or   
   configuration files, in the event of systemd - before /etc/fstab is   
   parsed.  This is distribution-specific.   
      
   Also note that tmpfs is not ramfs.  It's a virtual memory filesystem, so   
   its contents can be paged out to the swap partition when needed.
