Concepts

  • file sizes (logical versus blocks consumed)
  • mounting a fs
    • changes in filesystem hierarchy
    • concept of a "root" filesystem
    • privileges required
  • loopback mounts and files
  • holes in files
  • stat on files


Sample Questions

  • If a program "seek"'s on a zero length file to position 100,000 and then writes one byte, what would you expect the file's logical length to be? What about its physical size (space consumed on disk)?
