Spacewalk is a Linux and Solaris systems management solution. It allows you to inventory your systems (hardware and software information), install and update software on your systems, collect and distribute your custom software packages into manageable groups, provision (Kickstart) your systems, manage and deploy configuration files to your systems, monitor your systems, provision virtual guests, and start/stop/configure virtual guests.
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.
Graft provides a mechanism for managing multiple packages under a single directory hierarchy. It was inspired by both Depot (from Carnegie Mellon University) and Stow (by Bob Glickstein). Packages are installed in self-contained directory trees and symbolic links from a common area are made to the package files.
PAR is a cross-platform packaging and deployment tool, dubbed as a cross between Java's JAR and Perl2EXE/PerlApp. It can turn your Perl programs into ready-to-run executables, build and use PAR files into @INC to avoid version conflicts, turn CPAN module distributions into PAR distributions, or install/uninstall/sign/verify PAR distributions.
Aphid (the Apache/Perl HTTP Installation Daemon) provides a quick facility for compiling and installing the Apache Web server with support for SSL via mod_ssl, and with the embedded Perl interpreter provided by mod_perl. It downloads, compiles, and installs the software into the directory of your choice. Aphid places emphasis on providing an intuitive, browser-based interface and keeping a tiny distribution footprint. To date Aphid has been tested on Rehat Linux 6 and 6.2, FreeBSD 4.0, and Solaris 2.6 and 7.
Easy SVN is a subversion browser via the Web. It's easy because only a command line svn program and Perl are required to run it; no extra software needs to be installed. After configuring the Perl script as cgi-bin program, SVN repositories can be navigated, and entries viewed for contents, history, and diffs.
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.
