reUpNix: Reconfigurable and Updateable Embedded Systems for Embedded Linux Stacks

Explore a 19-minute video presentation from the LCTES 2023 conference introducing reUpNix, a methodology for creating reproducible, updateable, and reconfigurable embedded Linux stacks. Learn how the researchers address challenges in managing embedded Linux systems by leveraging NixOS, reducing installation size, implementing atomic system updates, and integrating third-party OCI images. Discover the potential benefits of reUpNix for multi-mission setups in scenarios where device deployment is costly, such as in space applications. Gain insights into the technical improvements achieved, including up to 86 percent reduction in basic installation size and up to 24 percent less on-disk space required for third-party images due to fine-grained file deduplication.
