[ale] Creating Filesystem

[baoh at linuxwizardry.com (Bao Ha)]

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.

  [ale] Creating Filesystem
  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 3.?? 
  It does not need to be saved at reboot 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
