Did you do that? The answer is no, I've looked for a step by step for doing this, but haven't come up with the correct search to find it. > > > The reason that I want to be able to resize the partition, is that I > > have another machine with a AMD64 3000+ CPU and a 250GB drive with FC3 > > as well.

Job done. I put in the 70GB drive to copy all the image files, and did a backup of the large root filesystem to have a backup.

Is there a place were I could get the step by step instructions.Using various combinations of words, I end up with from 40,000 to 5,000 pages. P.S. These are for my G4L - Ghost for Linux images that I've been working on.
