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.
SALI (Sara Automatic Linux Installer) is a tool that allows you to install Linux on multiple machines at once. It support several protocols for downloading by way of aria2 to install a machine. For example, BitTorrent and rsync are supported. SALI originates from SystemImager and still uses the same philosophy. It is a scalable method for performing unattended installation. SALI is mostly used in cluster setups.
Viper is a system for completely automated installation and configuration of Debian GNU/Linux-based systems. It uses a modern approach with debian-installer and puppet, works with existing Debian packages, and does not require any custom patching of either install media, client, or server. The basis of the whole system is an LDAP server containing all configuration data.
Portable Linux is a tool that lets you create bootable USB and removable drives using popular Live CDs based on Casper (like the Ubuntu family of distributions). It sports some unique features. The live setups it creates let you use the remaining disk space on your USB drive to store and transport files between computers, as usual. If your distribution supports persistence, the files and settings you edit on your live Linux distribution are persisted across reboots. Finally, you can access the area used to store your files from within your Linux distribution.
Nhopkg is a lightweight and powerful package manager system for Unix-like operating systems. Nhopkg can install, remove, update, search, and manage software packages in its own .nho format. Nhopkg aims to be a universal package manager. Because of this, Nhopkg isn't only a package manager, but is also a set of guidelines to pack up software for any machine. Therefore, to check package dependencies, Nhopkg searches for specific files instead of package names.
List2pkg is a program to create Slackware packages in a simple way. More precisely, given a list of files, it will create a Slackware package containing these files. A user trying to install that package will see the same files installed at the same locations they were on your system.
Urpkg is software to install programs in a safe and undoable way. It is able to see what files any given installation command creates, and list and remove them. You are able to restrict the installation command so that it only writes where you allow it to, and does not overwrite files from other packages. Urpkg is especially useful if you want to install programs from source, or create binary packages in an automated way. Under the hood, urpkg creates a user for each package it has to install, which prevents the installation command from run with root privileges. It can be seen as a "command tracer" that remembers what files a command created and prevents it from doing forbidden things. It is written in C but relies on some external commands, like GNU Find.
UnusedPkg is a diagnostic tool to search the oldest unused packages in your Linux system. UnusedPkg prints a sorted list with the size and number of days that a package has been idle. This helps you determine what packages can be manually removed to clean the system. It supports any apt-based distribution (tested on Debian and Ubuntu) and Slackware.
