Cobbler is a network installation and update server. It can be used to automatically set up PXE, install virtual guests, manage answer files, and reinstall existing Linux machines. Advanced features include importing distributions from DVDs and rsync mirrors, kickstart templating, integrated yum mirroring (integrated with the installer to make updates available at install time), creation of netboot ISOs, and built-in DHCP/DNS Management. Tools such as "cobbler triggers", a Python API, and an XMLRPC API allow integration with cobbler with the rest of your datacenter environment or other systems management applications. There is also a Web interface to simplify management of the install server. Cobbler supports RHEL 4+, Fedora, and derivative distributions, and is also able to install other popular distributions.
CD Shell is a scriptable menu system that provides the ability to create interactive multi-boot optical discs. It will make PC-bootable compact discs or DVDs that can select from several program loaders or kernels located on the disc, or boot from other local disk drives that are attached to the system.
Gentoo Linux is a versatile and fast Linux distribution for x86, PowerPC, Sparc, and Sparc64 that's geared towards Linux power users. Unlike other distros, it has an advanced package management system called Portage. Portage is a true ports system in the tradition of BSD ports, but is Python-based and sports a number of advanced features including dependencies, fine-grained package management, "fake" (OpenBSD-style) installs, path sandboxing, safe unmerging, system profiles, virtual packages, config file management, and more.
install4j is a cross platform Java installer that produces native launchers and installers for all major platforms. install4j offers an intuitive GUI that makes it easy to quickly define installation projects. A command line compiler and an integration for Apache ANT are included.
Rally is a software component with a user interface which allows a user to install, update, and remove packages on RPM based operating systems. Primary functions (downloading software packages from network repositories and their installation) may be performed in parallel. The user interface is split into two independent parts: a graphical one and a command line utility. The graphical interface contains package searching and category browsing functions. Rally assumes the Fedora project as a reference platform.
whohas is a command line tool that allows you to query several package collections at once. It currently supports Arch Linux (and AUR), Debian, Fedora, Gentoo, Mandriva, openSUSE, Slackware (and linuxpackages.net), Source Mage Linux, Ubuntu, FreeBSD, NetBSD, OpenBSD, Fink, and MacPorts repositories. whohas was designed to help package maintainers find ebuilds, pkgbuilds, and similar package definitions from other distributions to learn from. However, it can also be used by normal users who want to know which distribution provides certain packages, and which version of a given package is in use in each distribution or in each release of a distribution.
Yum (Yellow dog Updater, Modified) is an automatic updater and package installer/remover for RPM systems. It automatically computes dependencies and figures out what things should occur to install packages. It makes it easier to maintain groups of machines without having to manually update each one using rpm.
AutoRPM is a program that can do any combination of the following: mirror RPMs from an FTP site, keep installed RPMs consistent with an FTP site or local directory and keep installed RPMs in a cluster or network of systems consistent. It is highly flexible and contains a fully command-line driven interactive install mode (for installing RPMs from the queue or for installing RPMs from your system interactively). It also handles recursive dependencies, multiple versions of the same RPM, the same RPM with multiple architectures, and more. It does some of the same tasks as up2date and AutoUpdate.
