flashboot for OpenBSD is a set of makefiles, scripts, and support tools to build an OpenBSD image suitable for booting from read-only media, such as flash memory. The default image (smaller than 5Mb) is an image for a firewall/router with support for IPsec, SSH, IPv4 and IPv6 packet filtering, DHCP (client and server), and PPPoE. This image may be further trimmed or extended by editing the packing list files included in the distribution.
fli4l is a single-floppy Linux-based ISDN/DSL/ethernet-router. It features configuration with some simple ASCII-files, several possible connection-flavors (in/out/callback, and raw IP/PPP), channel bundling (an extra channel can be added through a Windows/Unix-client), configuration of multiple networks, least-cost routing, automatic choice of provider, display/calculation of connection times and costs, and a Windows/Unix client to control dial/hangup, monitor traffic and monitor incoming calls on ISDN (see screenshot).
SlimServer on DiskStation is an add-on package to the Synology DiskStation family of PowerPC and ARM9 based NAS devices providing the environment to run SlimDevice's SlimServer on it. It integrates into the DS administrative Web interface and comes with various user-friendly tools and scripts to maintain the installation. It supports all currently official features of Slimserver, such as Asian character display and on-the-fly transcoding of various music file formats. Popular third party plugins are supported as well.
footprint is a tool that makes it easier to create and manage kickstart files. It allows you to define systems, create profiles for systems, and macros per distribution. It can create kickstart files on the fly, make custom initrd (ramdisks), create custom bootfloppies, and can manage your DHCP and PXE configuration.
Gendist is a live CD generator system. It has nice features like multi-distribution CDs, support for grub, isolinux, and gfxboot boot managers, and a modules system for configuring your distribution in live mode. This system is independent from the kernel version (but need unionfs and squashfs support). It only works on Debian Sid or Ubuntu Dapper.
Grml is a live system (live CD) based on Debian. It includes a collection of GNU/Linux software especially for system administrators and users of texttools. It provides automatic hardware detection and its default shell is the zsh. You can use it e.g. as a rescue system, for analyzing systems/networks, or as a working environment. It is not necessary to install anything to a hard disk; you don't even need a hard disk to run it. Due to on-the-fly decompression, it includes more than 2 GB of software and documentation on the CD.
haveged is a daemon that feeds the /dev/random pool on Linux using an adaptation of the HArdware Volatile Entropy Gathering and Expansion algorithm invented at IRISA. The implementation attempts to be self-tuning on a wide variety of hardware and includes runtime validation testing. The tarball uses the GNU build mechanism and includes a devel sub-package, self test targets, init system options, and spec file samples for building an RPM. haveged may be used independently of the /dev/random interface through the filesystem at the command line. haveged functionality may be incorporated directly into other components directly through the devel sub-package.
