Debian 6.0 introduces a dependency based boot system, making system start-up faster and more robust due to parallel execution of boot scripts and correct dependency tracking between them. Upgrades to Debian GNU/Linux 6.0 from the previous release, Debian GNU/Linux 5.0 (codenamed "Lenny"), are automatically handled by the apt-get package management tool for most configurations.
