SystemImager automates the installation of Linux to masses of similar machines. Software distribution, configuration, and operating system updates are made easy, including updates from one Linux release to another. It can also be used for content distribution on Web servers. It is most useful in environments with large numbers of identical machines. Some typical environments include Internet server farms, high performance clusters, computer labs, and corporate desktop environments where all workstations have the same basic hardware configuration.
The JACAL Project is a suite of programs, scripts, guidelines, protocols, documentation, and diskettes that assist in quick, network based loads/builds of machines. It has been used to build 70 University lab machines from scratch (No OS) in two hours. This includes NT service packs and 80+ applications on the NT side.
UDPCast allows to send data simultaneously to many destinations on a local net. This can for instance be used to install entire classrooms of PCs at once. The advantage over using other methods (nfs, ftp, whatever) is that udpcast uses Ethernet's multicast abilities: it won't take longer to install 15 machines than it would to install 2. The tool comes with a busybox bootdisk for easy loading of the tool. However, udpcast can also be started from the command line of an already installed system, and can be used for other purposes than just system installation.
Replicator is a set of scripts to automate the duplication of a Debian GNU/Linux installation from one computer to another. Replicator makes an effort to take into account differences in hardware (like HD size, video card) and in software configuration (such as partitioning). After the initial configuration, the scripts will create a bootdisk that allows you to completely (re)install a Debian box by booting from the floppy and answering a yes/no question. It works with Debian 2.1 (stable) and frozen (potato).
pkgusage lists all the packages you have installed on your system, along with a number telling you how many days ago you last accessed any of the files in the package. This could be useful for cleaning out your hard drive. Pkgusage works with RPMs and Debian packages, and is written to be easily portable to other package managers as well.
The ESP Package Manager (EPM) is a simple tool that generates software and patch distributions in various formats, including AT&T software packages ("pkg") used by Solaris, Debian ("dpkg"), HP-UX software packages ("swinstall" or "depot"), IRIX Software Manager ("inst" or "tardist"), portable (installation and removal scripts with tar files), and Red Hat Package Manager ("RPM").
