Even as embedded system hardware processor speeds and storage sizes keep increasing, the need for reducing Linux distribution size remains, as hardware cost, upgrade bandwidth, and security concerns still are issues for developers. This presentation will discuss the history of embedded Linux distribution size, and then move on to techniques for reducing distribution size when using Yocto Project releases. The configuration changes done by the Yocto Project poky-tiny distribution will be walked through, with the size impact and drawbacks of each evaluated. Beyond that, the size impact of other commonly used packages and distribution features will be evaluated, with discussion on how to minimize image size when using them.
