The rPath Appliance Agent (rAA) is an extensible application framework for the administration of appliance devices through a Web-based user interface. The framework is comprised of individual component plugins which offer specialized functionality, such as a message log interface, user account preferences, system updates, and entitlement management capabilities. You can also develop and add plugins to the rAA framework, extending capabilities and functionality for your specific requirements.
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.
Sysinit is a system-initialization scheme for use with Linux and a daemon-management scheme for use with runit or daemontools. It provides a common interface to all functionality, and uses envdirs instead of sourced shell scripts or custom configuration files. It does error handling, handles dependencies gracefully and simply, and handles runlevels.
UPMS (Universal Package Managment System) is based on the BSD ports system, and can be used on any FHS 2.0 Linux-compatible distribution. UPMS has two level of dependencies checking: required and suggested. It also has an option to optimize everything that you build and install with it for your architecture.
deb-install is a command line tool that can install or show information about packages and files in several different formats. Whenever a program is installed using deb-install, it is converted into a .deb package beforehand, and thus can be removed with a simple "apt-get remove <name>". It currently supports apt-get, .deb, .rpm, .dsc, and .tar/.zip (source archives). Compression via gzip or bzip2 is handled automatically. If a needed tool is missing, deb-install asks whether it should install it.
