GNU Parted is a package for creating, destroying, resizing, checking, and copying partitions and the file systems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data between hard disks, and disk imaging. It contains a library, libparted, and a command-line frontend, parted, which also serves as a sample implementation and script backend.
Partition Logic is a partitioning and disk management tool for PC-compatible computers. It includes its own standalone operating system and GUI, and can fit on a single bootable floppy (or CD). It creates, modifies, resizes, deletes, formats, and moves partitions, and copies hard disks. It is based on the Visopsys operating system.
Apache Toolbox provides a means to easily compile Apache (IPv4/6) SSL, PHP(v3/v4), MySQL, Jakarta, a large number of modules (61 3rd party modules and 36 default Apache modules, static or as DSOs), and GD libraries with PNG+JPEG+Freetype2+zlib support. It is fully customizable and menu-driven. Everything is compiled from source, and wget is used to download any missing modules. It can also check for RPMs that might cause problems and create an RPM with your selections.
The Linux From Scratch project is intended for Linux users who want to build their own custom Linux system. Reasons for wanting to build such a system are diverse. Perhaps you want to get into more detail as to what happens behind the scenes. Perhaps you are fed up with the bloated standard distributions. Or perhaps you don't want to rely on pre-compiled binaries out of concerns for security.
TrinityOS is a step-by-step, example-driven HOWTO on building a very functional Linux box with strong security in mind. TrinityOS is well known for its strong packet firewall ruleset, Chrooted and Split DNS (v9 and v8), secured Sendmail (8.x), Linux PPTP, Serial consoles and Reverse TELNET, DHCPd, SSHd, UPSes, system performance tuning, the automated TrinityOS-Security implementation scripts, and much more.
Einarc is a unified storage RAID command line interface and an API that provides management for various hardware/software RAID devices, uniting them all in a single paradigm. Einarc works as a translator that makes it possible for a user to control all these devices using simple terms like "physical disc", "logical disc", "adapter", etc., while transparently converting these requests to proprietary RAID paradigms.
Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Rather than having a full distribution come from a single vendor, it allows administrators and developers to branch a distribution, keeping the pieces which fit their environment while grabbing components from other repositories across the Internet.
