NeroLINUX is flexible graphical application to assist in burning writable CDs and DVDs in many formats. It supports all types of internal and external recorders that are supported by the API of the established Nero application for Windows. It features kernel optimizations for both 2.4 and 2.6 kernels, digital audio extraction, FreeDB support, and USB hotplugging. Video editing capabilities are not yet included.
Kerrighed is a Single System Image operating system (SSI) for clusters. It offers the view of a unique SMP machine on top of a cluster of standard PCs. The goals are high performance of applications, high availability of the cluster, efficient resource management, high customizability of the operating system, and ease of use. It is implemented as an extension to Linux operating system (a set of Linux modules and a small patch to the kernel).
eINIT is an alternative init system. It's quite fast, since it can potentially be used without the help of any scripting at all, but it is still flexible and extremely modular. The focus is on speed and parallelisation, mostly with embedded devices and low-downtime servers in mind, and benchmarks do suggest that it's doing a fairly good job at that. It compiles cleanly (and should thus work, provided someone writes appropriate modules) on Linux, FreeBSD, and Darwin/Mac OS X.
INSERT (the Inside Security Rescue Toolkit) aims to be a multi-functional, multi-purpose disaster recovery and network analysis system. It boots from a credit card-sized CD-ROM and is basically a stripped-down version of Knoppix. It features good hardware detection, fluxbox, emelfm, links-hacked, ssh, tcpdump, nmap, chntpwd, and much more. It provides full read-write support for NTFS partitions (using ntfs-3g), and the ClamAV virus scanner (including a fairly recent signature database and a GUI). It provides partition handling with gParted and also has a network boot facility.
Instant Boot Server allows you to set up a Debian GNU/Linux chroot environment and install a TFTP boot server onto it. Three "boot methods" are provided, one for providing the clients with the Debian Installer, one for providing an NFS root, and one for testing/playing with custom-built kernels and initrd images. The boot server is started and stopped on demand. The main program (shell script) is extensible, and may be used to serve as a platform for adding other server types.
Hotplug2 is aimed at early Linux user space, i.e. initramfs or initrd, and possibly also at embedded devices (such as WRT-like routers) or very weak machines, such as 386/486. It connects to the uevent netlink socket and reads events. The application generally operates in two modes: dumb and smart.
GRUB for DOS is a rebuild of the GNU GRUB boot manager for DOS, and can be run under real mode DOS. It also has many new features. It can be booted through BOOT.INI of Windows (grldr) and kexec of Linux (grub.exe). It can directly boot NTLDR (WindowsNT/2K/XP), IO.SYS (Windows9x/Me) and KERNEL.SYS (FreeDOS). The disk emulation feature is another enhancement over GNU GRUB, and can be used to run legacy DOS/Windows9x systems with floppy or hard disk images.
