Overview

Dell System Update (DSU) is an improved version of Dell OpenManage Linux Repository (DLR) to

distribute Dell updates for Linux systems. The DSU distributes:

• OpenManage Server Administrator

• BIOS and firmware updates for different servers

DSU extensively uses Yum and Zypper.

• Yellowdog Updater, Modified (Yum)

Yum is an open source command line package management utility used for Linux operating systems.

Yum primarily helps to do automatic updates, package and dependency management, mainly for

RedHat Package Manager (RPM) based distributions. Yum has a command line interface and it is

implemented in the Python programming language. Yum is mostly used to update and manage Red

Hat Enterprise Linux systems. Yum has a great informational output and syntax.

• Zypper

Zypper is used for installing, removing, updating, and querying software packages of local and remote

networked media. It has been extensively used for the openSUSE operating systems. It is a package

management engine that powers Linux applications like Yet another Setup Tool (YaST). Zypper can

download several update packages, and install them at once. Zypper is one of the fastest and

powerful package manager for the Linux environment.
