I cant speak to the linux cuz I have no clue how it works filewise etc.
cant you do this instead......make some ghost boot floppies? That is how I always use ghost.....I make my images onto burned cd's.
boot from the ghost floppy
choose "disc to image"
choose the cdburner as the destination
burn the image to the disk(s)
then to reimage a hard drive you would just boot from the floppies and do "restore from image" and point to the image on the cd's
------
otherwise you could put the model hard drive in the other comp and boot from the ghost floppy and do "disk to image" with the model hard drive as the source and the big storage hard drive as the destintation.

Probably 3 or 4 ways to get it done.
