Cobbler is a network installation and update server. It can be used to automatically set up PXE, install virtual guests, manage answer files, and reinstall existing Linux machines. Advanced features include importing distributions from DVDs and rsync mirrors, kickstart templating, integrated yum mirroring (integrated with the installer to make updates available at install time), creation of netboot ISOs, and built-in DHCP/DNS Management. Tools such as "cobbler triggers", a Python API, and an XMLRPC API allow integration with cobbler with the rest of your datacenter environment or other systems management applications. There is also a Web interface to simplify management of the install server. Cobbler supports RHEL 4+, Fedora, and derivative distributions, and is also able to install other popular distributions.
systemd is a system and service manager for Linux, compatible with SysV and LSB init scripts. It provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux cgroups, supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can work as a drop-in replacement for sysvinit.
runit is a cross-platform Unix init scheme with service supervision; a replacement for sysvinit and other init schemes. It runs on GNU/Linux, *BSD, Mac OS X, and Solaris, and can easily be adapted to other Unix operating systems. runit implements a simple three-stage concept. Stage 1 performs the system's one-time initialization tasks. Stage 2 starts the system's uptime services (via the runsvdir program). Stage 3 handles the tasks necessary to shutdown and halt or reboot.
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.
gBootRoot makes the construction and development of distributions fun and simple with its Root Methods (Yard) and user-mode-linux test bed. Finish the product with a Boot Method (2-disk compression supported). Normal (non-root) users can make root filesystems and boot disks. It includes the make_debian script to create a testable user-mode-linux base Debian system, add-ons to enhance methods, and an MTD Emulator useful for running distributions made with the jffs/jffs2 filesystem.
GAG is a Graphical Boot Manager with a lot of features. It doesn't need a partition, it works with primary and extended partitions in every hard disk, it has a lot of icons, it allows you to put passwords for each operating system, it can swap hard disks and it can be tested from diskette. The SafeBoot feature allows you to boot your hard disk even if GAG is overwritten. It includes extensive support for many languages and keyboard types.
The Auditor security collection is a live-system based on KNOPPIX. It provides tools for analyzing the security of a system. It features a menu structure that reflects the stages of a security check: foot-printing, analysis, scanning, wireless, brute-forcing, cracking. In addition to about 300 security tools, the collection includes background information regarding standard configuration and passwords, truly extensive word lists, and more mundane productivity tools.
daemon turns other processes into daemons. There are many tedious tasks that need to be performed to correctly set up a daemon process; daemon performs these tasks for other processes. This is useful for writing daemons in languages other than C, C++, or Perl (e.g. sh, Java). If you want to write daemons in languages that can link against C functions (e.g. C, C++), see libslack, which contains the core functionality of daemon.
