    You'll find that Linux filesystems don't fragment anywhere near as much
    as the Windows filesystems. Case in point: my crappy little Dell XPS
    M200s is 1.5% fragmented, and it's on 24x7 (since it's my multimedia,
    network storage and print server). My laptop's boot and root partitions
    (simple, default partition setup) are 0% and 2% fragmented. It's been
    running RH9 and was recently upgraded to FC1.

    If things do get out of hand in some way and your filesystems do start
    to fragment more than, say, 10%, you can simply copy everything out of
    the affected filesystem, and copy the data back. That should eliminate
    the fragmentation.

    However, I think you'll find fragmentation is going to be non-existent.
