Gentoo Linux, or Why in the World You Should Compile EverythingDonnie Berkholz
Gentoo Linux is a special flavor of Linux that can be automatically optimized and customized for just about any application or need. Extreme performance, configurability and a top-notch user and developer community are all hallmarks of the Gentoo experience.
As a leader of Gentoo, I will provide an overview of how it works from a developer's and a user's point of view, and why you should be running it especially if you're:
- In need of an awesome development environment;
- Interested in learning what's inside the black box of Linux;
- OCD about having a perfectly configured setup; or
- Building an embedded, minimal system or a high-performance cluster.
If there's interest, I can also talk about future developments on the horizon for Gentoo, package management in general, etc.

Immutable Image-Based Operating Systems - EW2024.pdfDrew Moseley
This document discusses immutable image-based operating systems. It begins with definitions, explaining that immutable systems have read-only critical components and use separate mechanisms for user data and applications. The conceptual architecture is described as updating the entire OS image rather than individual packages. Benefits include atomic updates and reproducibility, while drawbacks include less flexibility and required reboots. Technologies like libostree and Btrfs snapshots are discussed. Examples of desktop and embedded immutable systems are provided, along with references for further information.
Linux is a widely used open source operating system kernel that can also refer to full operating system distributions. It is commonly used in embedded systems due to its portability, modularity, and ability to run on hardware with limited resources. Device drivers can be dynamically loaded and unloaded from the Linux kernel as modules, allowing new functionality to be added without rebooting the system. This makes Linux well-suited for embedded device development.
Blocks is a cool concept and is very much needed for performance improvements and responsiveness. GCD helps run blocks effortlessly by scheduling on a desired queue, priority and lots more.

Building Embedded Linux Systems IntroductionSherif Mousa
This document provides an introduction to embedded Linux. It defines embedded Linux as using the Linux kernel and customizing user-space libraries and utilities for applications in consumer electronics, military, medical, and other industries. Creating an embedded Linux system involves selecting the right components to build the final system. A cross-compiler is used to build code for the target platform on the host development machine. Key components of an embedded Linux system include the bootloader, Linux kernel, filesystem, configuration files, C library, commands, and user applications.
eZ Publish 5: from zero to automated deployment (and no regressions!) in one ...Gaetano Giunta
1. The workshop will cover Docker, managing environments, database changes, and automated deployments for eZPublish websites.
2. A Docker stack is proposed that includes containers for Apache, MySQL, Solr, PHP, and other tools to replicate a production environment for development. Configuration and code are mounted as volumes.
3. Managing environments involves storing settings in the code repository and using symlinks to deploy different configurations. Database changes should be managed via migration scripts rather than connecting directly to a shared database.
4. Automating deployments is important and involves tasks like updating code, the database, caches and reindexing content. The same deployment script should be used for development and production. Testing websites is also recommended.

DevSecOps: Continuous Engineering with Security by Design: Challenges and Sol...CREST
Some key takeaways from this talk are outlined below. The main focus area for researchers in DevSecOps is automation and tool usage. Older
technologies, such as SAST & DAST tools have drawbacks that affect DevSecOps goals.
Shift-left security and continuous security assessment are two key recommendations. These
practices prioritise security in a continuous manner throughout the deployment cycle.
Inability to automate traditionally manual security practices is a significant problem in this
field. These practices are hard to be fully integrated with the continuous practices of DevOps.
Even though cultural or human aspects are critical for DevSecOps success, these has not
been much done in the state-of-the-art and the state-of-the-practice domains
Adopting DevSecOps principles or practices in various complex, resource-constrained, and
highly regulated infrastructures is a growing area of research. More empirically evaluated
solutions are needed to ensure wider adoption of such tools or frameworks

ECSA 2023 Ubuntu Case Study
1. Analyzing the Evolution of Inter-package
Dependencies in Operating Systems: A
Case Study of Ubuntu
Victor Prokhorenko, Chadni Islam,
Muhammad Ali Babar
2. Overview
Software dependencies and complexity
Operating Systems context
DepEx framework - Dependency extraction
Ubuntu – Findings
Future work directions and enhancements
3. Types of software dependencies
• Code libraries (source or binary)
• Network sockets
• UNIX domain sockets
• Pipes
• File-based
• Run-time code provisioning
• Downloading from external source
• Generated by external applications
• Discoverable and undiscoverable
4. Code libraries
• Available in source form at compile time
• Used through various form of Import- and Include-like statements
• Can be in-lined or embedded, thus eliminating external dependency
• Dynamically loadable at run time
• Typically met in form of .so and .dll files
• Can have recursive dependencies of their own
5. Binary Dynamically Loadable Libraries
• Required to be present in the system for a given application to start
• Required to be located in a discoverable “place”
• Required to contain the necessary functionality
• List of exported functions
• Versioning considerations
• Source code may be inaccessible
• Sourced from:
• Application bundle
• Pre-existing Operating System
7. Complexity aspect: dependency-based metrics
• How do dependencies
reflect application
complexity?
• How do dependencies
reflect library importance?
• Four metrics investigated:
Presence, Coverage,
Occurrence, Usage
• Developer-facing
complexity vs. recursion
8. Operating system context
• Single application development phase
• Testing through compilation and execution
• Multiple tools: compiler, IDE, tests, debuggers
• Multiple applications usage phase
• Automatic dependency installation (apt install)
• Library version conflicts: versioned names
• Bundling: archive, container, VM
• Base system inflation
9. System-wide dependencies observability
• Emergent high-level architecture appears as a result of combining multiple
independently-developed applications
• Constant system modifications and updates lead to lack of stable picture
• Lack of bird’s eye view:
• Are there any libraries missing that are required by executables in the system?
Which ones?
• Which executables would not be able to run due to the lack of required libraries?
• What are the most popular/critical libraries (i.e. required by most number of
executables)? Least popular?
• Which libraries are present in the system but not required by any executable?
10. DepEx: Dependency Extractor framework
• Plugin-based architecture
• Presence and Coverage metrics
• Scans file system and stores
discovered dependencies in a
structured database
• Current development targeted at
run-time file modifications tracking
11. Ubuntu case study
• Why Ubuntu?
• High popularity
• Consistent archives
• Detailed release notes
• Long history – chance to find evolutionary patterns
• Technical challenges
• Disk space requirements
• Image format and compression changed over time
12. Ubuntu case study: statistics
• 84 consecutive versions (5.04 to 23.04)
• 18 years of history
• 114GB of compressed images
• 9.8 million total files
• Over 408000 total binaries and executables
• Almost 2 millions of library-level dependencies extracted
18. Ubuntu: most popular libraries (direct)

DIRECT USES
21. Conclusion
• Executables with a high number of recursive dependencies can be removed
• “Complexity” comes from large number of subsystems: image formats, setup
• Highly popular libraries are here to stay
• A large number of libraries (up to three quarters) are not explicitly required
• Plugins – discovered and loaded through a different mechanism
• Shipped “just in case” for applications that would likely be installed
• While periodic cleanups occur in practice, averages still steadily grow
• Developer-facing complexity tends to be controlled
22. Future work directions and enhancements
• More plugins for more executable types
• Network awareness
• Run-time file activity tracking and dependency graph updating
• Real-time system health monitoring
• Missing libraries, broken executables, missing links
• Recovery/fixing recommendations
• Most required missing library?
• Last file event impact?
