12. Software Installation and Management
The installation, configuration, and management of software is a large part of most sysadmins’ jobs. Administrators respond to installation and configuration requests from users, apply updates to fix security problems, and supervise transitions to new software releases that may offer both new features and incompatibilities. Generally speaking, administrators perform all of the following tasks:
• Automating mass installations of operating systems
• Maintaining custom OS configurations for the local environment
• Keeping systems and applications patched and up to date
• Managing add-on software packages
