Explore embedded Linux size reduction techniques in this comprehensive conference talk. Learn approaches for minimizing the kernel, individual applications, and entire filesystem to run Linux on systems with limited RAM and storage resources or to achieve faster boot times. Discover benchmarks illustrating potential savings for each method, and gain insights from participant experiences and ideas for further improvements. Delve into topics such as GCC optimizations, Clang vs GCC comparisons, kernel configuration options, user space optimizations, and recent achievements in the field. Benefit from Michael Opdenacker's expertise as the founder of Free Electrons, known for its freely available training materials on the Linux kernel and embedded Linux.
