KateOS was a Linux distribution originally based on Slackware. It was designed for intermediate users. Its package management system used so called TGZex (.tgz) packages, which unlike Slackware packages support dependency tracking (optional), internationalized descriptions, and were designed for ease of update. There were two native tools for package management: PKG and Updateos. The last version released was KateOS III (3.6), including as a Live CD, in 2007. History The KateOS project was founded at the end of 2003 by Damian Rakowski. Kate Linux 1.0 Rabbit (series I) The first version of the system was published on 2004-10-09. The system was based on Slackware 9.0. Due to the problems with the main server which worked only infrequently, hardly anyone learned about the existence of Kate 1.0. After a move to another server, the project has begun to gradually acquire users. After some time, Kate 1.0.1 (a fix release including UpdatePack 1), and a Live version were published. Kate Linux 2.0 Zyklon (series II) Version 2.0 was published on 2005-04-09, and was no longer based on Slackware. It was a long-term edition, the base for further development. It was also the first edition using Linux 2.6. On 2005-05-06 the name of the project has been changed to KateOS. On 2005-05-22 version 2.0.1 was published, providing a tool for managing and remote updating the TGZex packages. The tool was called Updates, and was written by Piotr Korzuszek. On 2005-06-23 version 2.1 was published. Updates now could install packages remotely. On 12 August 2005, the first Live edition of series II was published. It had a more distinctive graphical design, used the squashfs technology (2 GB of data packed on just one CD) and unionfs. On 2005-10-13 the last version of Version II was published - 2.3. Updates gained new possibilities, and the system had a better hardware autodetection with the Discover tool. KateOS 3.0 Virgen (series III) On 12 April 2006 the first snapshot of KateOS 3.0 was published. On 2006-07-09 version 3.0.1 was published. The packaging system was completely rewritten resulting in the PKG and Updates2 tools, and the libupdateos and libsmarttools libraries. The functionality of the TGZex packages was widened, this time to include dependency tracking and descriptions in many languages. The installation process was simplified to allow a full install in only 15 minutes. The system used udev, D-Bus and HAL to detect hardware and mount devices automatically. On
