OBLISK (Open Binary Linux Install System Kit) aims to make any package install on any modern GNU/Linux system. OBLISK packages are sent in an appdir-like package and can be run entirely in place, but also have an installer, which makes it possible for them to be installed to /usr or any other path.
makeself is a small shell script that generates a self-extractable compressed TAR archive from a directory. The resulting file appears as a shell script, and can be launched as is. The archive will then uncompress itself to a temporary directory and an arbitrary command will be executed (for example, an installation script). This is pretty similar to archives generated with WinZip Self-Extractor in the Windows world.
mkCDrec (Make CD-ROM Recovery) makes a bootable (El Torito) disaster recovery image, including backups of the Linux system to one or more CD-ROM(s) (multi-volume sets). Otherwise, the backups can be stored on another disk, NFS/CIFS disk, or (remote) tape. After a disk crash or system intrusion, the system can be booted from the CD-ROM and one can restore the complete system as it was. It also features disk cloning, which allows one to restore a disk to another disk (the destination disk does not have to be of the same size, as it calculates the partition layout itself). Currently, ext2, ext3, minix, MS-DOS, FAT, VFAT, Reiserfs, XFS, and JFS filesystems are supported. It can restore disks in Software RAID and LVM mode. It supports the One Button Disaster Recovery (OBDR) mode, which simulates a bootable CD-ROM on tape.
Elektra is a universal hierarchical configuration store, similar to GConf and the Windows Registry. It allows programs to read and save their configurations with a consistent API, and allows them to be aware of other applications' configurations, leveraging easy application integration. While architecturally similar to other OS registries, Elektra does not have most of the problems found in those implementations. Elektra includes a library, an API, and commandline and GUI tools for administration tasks.
FAI (fully automatic installation) is a non-interactive system to install a Debian GNU/Linux operating system on a group of PCs or a Linux cluster. After installation, the systems are fully configured and ready to run. It is a scalable method for performing unattended installation and updating. Changes to the configuration files of the operating system are made by cfengine, shell, and Perl scripts.
