I've gotten ghost to work with FC3, but not exactly sure what 
changed got it to work. I think it was probable doing a shutdown -r -F 
now , and then it failed, and I log in with root id, and run fsck 
manually. Then ghost wouldn't get the the sector not found error.

Other options include using G4U, Ghost for Unix, which is a BSD 
boot diskette that uploads images to an ftp server using DD and 
Gzip. It worked fine with the problem with ghost. Make sure to clear 
unused space thou. I did an FC3 install with everything option, and 
the fist image was about 12GB from my 80GB drive. I then zeroed 
out the unused space, and redid the image, and it was 2.5GB. 

The is also a G4L program, which is ghost for linux. There is a 
dispute over it being a copy of G4U, but the current version looks 
nothing like the G4U, single 2000 line script verus separate scripts 
to upload and slurp disk and partitions by G4U. The G4U site shows 
an earlier version of g4l, that seems to be a close copy, but I'm not 
sure that and the current one are related. The G4L has a lot more in 
the script, and also supports bzip2 compression. 

I've used G4U and G4L to make images and restore them, and they 
take about the same time, and produce about the same image size. 
Perhaps even the exact images if you do both with gzip, but I would 
have to do an image with one, and then the other to be sure. 

G4U version 2 is now a two disk boot up, but the older version is 
availabe as a CD image, and is also included on the ultimate boot 
CD. The G4L is a CD only image. Note: to use it, you have to give 
anonymous write access to the an img directory. G4U uses DHCP, 
but G4L you do things thru the script.

Both G4U and G4L are free. They don't let you resize the images, 
so you need to use the same size drives or larger to restore the 
images.
