Augeas is a configuration API and editing tool. It parses common configuration files like /etc/hosts or /etc/grub.conf in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native configuration files.
Installwatch is a simple utility which keeps track of which files are created and modified during the installation of a new program. It's fast and easy to use. It doesn't require a "pre-install" phase because it monitors processes while they run. Installwatch works with every dynamically linked ELF program, by intercepting system calls that cause file system alterations.
The GNOME NetworkManager is a set of co-operative tools that make networking simple and straightforward. Whether wireless or wired, NetworkManager allows you to quickly move from one network to another: once a network has been configured and joined once, it can be detected and re-joined automatically at a later date. It was designed to auto-detect as much information as possible, seamlessly switches connections when necessary, and provides immediate feedback of the network state to users and applications.
Omnitty is a curses-based program that allows you to log into several machines simultaneously and interact with them, selectively directing input to individual machines or groups of selected machines. You can run both line-oriented and screen-oriented in the target machines, because it has built- in terminal emulation capability. When the window is large enough, Omnitty also displays a "summary area" for each machine, in which it shows what the latest output from the machine was, so you can have an idea of what is going on in each machine.
PIKT is cross-categorical, multi-purpose software for monitoring and configuring computer systems, administering networks, organizing system security, and much more. PIKT is intended primarily for system monitoring, and secondarily for configuration management, but its versatility and extensibility evoke many other wide-ranging uses. PIKT consists of a sophisticated, feature-rich file preprocessor; an innovative scripting language with unique labor-saving features; a flexible, centrally directed process scheduler; a customizing file installer; a collection of powerful command-line extensions; and other useful tools.
EPOR is an extensible package organiser for Unix-like systems. It's written to trace filesystem changes (something being installed) and save this information in a simple text database (this, as any other provided feature, is customisable via the embedded Guile interpreter). Database entries contain information supplied by the command line (package name, version, etc.) and traced by filesystem changes (new directories, files, etc.). This is achieved using the "LD_PRELOAD method''.
qmail-installer is a shell script that asks the user a few configuration questions, and then downloads, patches, installs, and configures qmail and its dependencies. Currently, the script installs daemontools and ucspi-tcp, and optionally qmailanalog, the SMTP AUTH patch, the qmail-queue patch, and the virus-scan-zip patch. The installer offers a number of modes (outbound only, outbound only with SMTP, normal, and normal with POP). The qmail installation performed by this script is compliant with Dan Bernstein's licensing, and is very close to an LWQ installation.
