Demystifying Systemd for Embedded Systems

Demystifying Systemd for Embedded Systems - Gustavo Sverzut Barbieri, ProFUSION Embedded Systems Embedded systems often have great goals such as fast boot and reliable execution, management and isolation of services. However due lack of understanding, some myths and great deal of FUD they go with custom hackish implementations based on shell scripts and sysvinit-like replacements like busybox. This presentation will cover experiences to slim down systemd footprint by disabling its components in order to compare apples-to-apples, then show how systemd scales up in a nice linear way, while alternatives start to barf when many components must be put together to cover networking, timed tasks, logging, dynamic device behavior and services babysitting and isolation. The presentation concludes why Ostro Project decided to mandate systemd in this distribution targeted at Internet of Things.
