  I 
  don't think you can do much about the superblocks.?? Why do you 
  
  have 
  to format the disk every time during bootup?

  Can 
  you expand an tar ball containing an empty filesystem 
which
  will 
  overwrite whatever on the disk?

  I 
  don't think you can keep it under 10 sec, though.

    I'm creating a network appliance that has roughly 20GB of 
    disk space.?? At each system boot, I want to 
    recreate the filesystem on the 20GB of read writable <FONT 
    size=2>partition.?? The facts are below: 
    1.?? The space is big 2.?? 
    It will only store trival logs that are needed <FONT 
    size=2>3.?? It does not need to be saved at reboot <FONT 
    size=2>4.?? I do not need supreblocks all over the place. 
    Questions 1.?? Can I use jsut 2 
    superblocks 2.?? Can I create a loopback image, 
    format it, and dd just wat is needed so <FONT 
    size=2>?????? at bootup I can use dd instead of mke2fs? 
    3.?? Can I get this to happen at bootup in under 10 
    seconds? 
    Thanks, Chris
