title: How to interpret /proc/mounts?
body: <p>When i do the following.</p>
  
  <pre><code>"cat /proc/mounts".
  tmpfs /export/ftp/import tmpfs rw,relatime,size=102400k 0 0
  tmpfs /export/ftp/export tmpfs rw,relatime,size=10240k,mode=755 0 0
  </code></pre>
  
  <p>The documentation of embedded device said that import and export are located in DRAM</p>
  
  <p>However in other equipment</p>
  
  <pre><code>ubi18_0 /nvdata1/temporary-download ubifs rw,sync 0 0
  ubi18_0 /export/ftp/import ubifs rw,sync 0 0
  ubi18_0 /export/http/import ubifs rw,sync 0 0
  tmpfs /export/ftp/export tmpfs rw,size=10240k,mode=755 0 0
  </code></pre>
  
  <p>The documentation of embedded device said that  import is located in NAND and export are located in DRAM.</p>
  
  <p>I really do not know what resides in DRAM, NAND, NOR.</p>
  
  <p>The basic knowledge i have in our equiment is that
  NOR has u-boot.
  NAND has kernel and rootfs.</p>
