How to build a solid distribution?
3
SUSE Maintenance
• Born in September 2001
• Linux Maintenance simply didn't exist before
• Triggered by needs of s390 mainframe customers
4
What is Maintenance?
• Everything that happens after a product or service pack is released
• Security updates and bug fixes
• Released periodically
• Long Term Service Pack Support (LTSS)
5
Updates – Do I really need them?
• “Has been running without problems for ages!”
• “Better not touch a running system!”
• “Not connected to the internet!”
6
Challenges
• Fix bugs, but no change of functionality
• Backport fixes from upstream
– Examples: kernel, openssl
• Packages continuously getting fixes
– Examples: xen, kvm, libvirt
7
Challenges
• No regressions
– No new bug in bug fix
– ABI, API compatible
– All PTFs included
• No feedback for PTFs (Program Temporary Fix)
• Huge variety of workloads and hardware at customer's sites or daily users
• Update description from user's point of view
8
Principles of Updates
• Minimal changes
• No new features
• No version updates
• Regression testing
• Fix for all supported architectures
9
openSUSE maintenance process

11
Quality Assurance
12
Quality Assurance
• Updates must pass QA
• Bug fix tests
• Regression tests
• Automatic and manual tests
13
openQA - https://openqa.opensuse.org/
• Testing framework
• Tests operating systems and applications
• UI and console testing
• Tests like a user
– Sends keyboard and mouse input
– “Reads” screen output
– Compares screen output to expected images
– Reads text from serial console
