Automate Linux installation and recovery

SystemImager has many advantages over traditional imaging methods. It uses rsync to store the image remotely, and can do a backup or full install in just three to five minutes. Images are complete copies of a filesystem, and their files can be edited. Images on a server can be updated when a change is made to a client, and only the changes need be copied over to the image. You can also make changes to the image on the server and push it out to clients; once again, only the changes are copied. SystemImager also supports auto-installation; clients can receive an image based on their MAC addresses.
