Super Grub Disk is a bootable floppy or CDROM that is oriented towards system rescue, specifically for repairing the booting process. Super Grub Disk is simply a Grub Disk with a lot of useful menus. It can activate partitions, boot partitions, boot MBRs, boot your former OS (Linux or another one) by loading menu.lst from your hard disk, automatically restore Grub on your MBR, swap hard disks in the BIOS, and boot from any available disk device. It has multi-language support, and allows you to change the keyboard layout of your shell.
Simple Package Manager (SPM) is intended to operate in a way similar to existing package managers (apt, dpkg, Pacman, etc.). Instead of supporting a centralized package repository, SPM allows remote packages to be downloaded and installed automatically, given their URL. This allows a developer to package and distribute software via a package management system without having to worry about the many different formats and Linux distribution repositories.
Puppet lets you centrally manage every important aspect of your system using a cross-platform specification language that manages all the separate elements normally aggregated in different files, including users, cron jobs, and hosts, along with obviously discrete elements like packages, services, and files. Its simple declarative specification language provides powerful classing abilities for drawing out the similarities between hosts while allowing them to be as specific as necessary, and it handles dependency and prerequisite relationships between objects clearly and explicitly.
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.
