title: What is the best file system for a small ramdisk under Linux?
body: <p>An embedded Linux system I am working on has a 4MB ram disk.  It is currently formatted with ext2.  It seems that even when empty, there is only about 50% free space !</p>
  
  <p>At the moment, it is used for about 50 smallish (1 or 2KB) files that total about 300KB.</p>
  
  <p>Is there a better filing system to use in this case (FAT32?).  </p>
  
  <p>I can't make the ram disk any bigger.  This system only has 512MB of RAM in total.  It's running a very specific version of Debian from years ago, which also can't be changed.</p>
  
  <p><strong>Edit:</strong>
  This seems to be a different problem than I describe.  I've just rebooted and when empty, the ram disk is only 1% full.</p>
