g4u ("ghost for unix") is a NetBSD-based bootfloppy/CD-ROM that allows easy cloning of PC harddisks to deploy a common setup on a number of PCs using FTP. The floppy/CD offers two functions. First is to upload the compressed image of a local harddisk to a FTP server. Other is to restore that image via FTP, uncompress it and write it back to disk; network configuration is fetched via DHCP. As the harddisk is processed as a image, any filesystem and operating system can be deployed using g4u.
