[20091025] Harddisk image cloning for Unix - g4u 2.4 released
g4u ("ghosting for unix") version 2.4 has been released. g4u is a NetBSD-based bootfloppy/CD-ROM that allows easy cloning of PC harddisks to deploy a common set up on a number of PCs using FTP. The floppy/CD offers two functions. The first is to upload the compressed image of a local harddisk to a FTP server, the 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 an image, any filesystem and operating system can be deployed using g4u. Easy cloning of local disks as well as partitions is also supported.

Three years of time have passed since the last full release of g4u. Here's a list of what's new / changes in g4u 2.4:

  • Major new supported device types include bluetooth keyboards and SD/MMC cards - feedback highly appreciated!
  • Lots of new drivers. Too many to list, please see the g4u section of my blog at for details.
  • Based on the NetBSD development version from Sep 2009
  • Source builds native and without root privileges on NetBSD 5.0 and crossbuilds also without root privileges from Mac OS X (tested) and probably others (untested; expected: Solaris, Linux).
The g4u 2.4 release is available on the g4u homeage at
