Clonezilla, based on DRBL, Partition Image, ntfsclone, and udpcast, allows you can massively clone many (40 plus!) computers simultaneously. Unlike G4U (Ghost for Unix) or G4L (Ghost for Linux),
Clonezilla saves and restores only used blocks in the harddisk. This
increases the clone effiency. At the NCHC’s Classroom C, Clonezilla was
used to clone 41 computers simultaneously. It took about 50 minutes to
clone a 5.6 GBytes system image to all 41 computers via unicasting and
only about 10 minutes via multicasting!
