If you want to change actions for single packages, right-click a package in the package view and choose an action. When debugging a problem, you sometimes need to temporarily install a lot of -debuginfo packages which give you more information about running processes.

Automated Installation of Linux Systems Using YaST Dirk Hohndel and Fabian Herschel – SuSE Rhein/Main AG ABSTRACT The paper describes how to allow a customized automated installation of Linux. This is possible via CDRom, network or tape, using a special boot disk that describes the system that should be set up and either standard SuSE Linux CDs, customized install CDs, an appropriately configured installation server, or a tape backup of an existing machine. A control file on the boot disk and additional (optional) control files on the install medium specify which settings should be used and which packages should be installed. This includes settings like language, key table, network setup, hard disk partitioning, packages to install, etc. After giving a quick overview of the syntax and capabilities of this installation method, considerations about how to plan the automated installation at larger sites are presented.

  • Package Management Security
    Package Management Security Justin Cappos, Justin Samuel, Scott Baker, John H. Hartman University of Arizona Computer Science Department {justin, jsamuel, bakers, jhh}@cs.arizona.edu Abstract Package management is the task of determining which packages should be installed on a host and then downloading and installing those packages. This paper examines the popular package managers APT and YUM and presents nine feasible attacks on them. There are attacks that install malicious packages, deny users package updates, or cause the host to crash. This work identifies three rules of package management security: don’t trust the repository, the trusted entity with the most information should be the one who signs, and don’t install untrusted packages. The violation of these rules leads to the described vulnerabilities. Unfortunately, many of the flaws are architectural in nature, so repair requires more than patches to APT and YUM. While the rules of package management security argue that the design of existing package managers is insufficient, they do not prescribe how to provide security. This led to the development of three de- sign principles for building a secure package manager: selective trust delegation, customized repository views, and explicitly treating the repository as untrusted. These principles were used to construct a pack- age manager Stork which is not vulnerable to the attacks identified for YUM and APT. Stork has been in use for four years and has managed over half a million clients. 1 Introduction Package managers are a popular way to distribute software (bundled into archives called packages) for modern operating systems [4, 11, 37].
