In Debian, there is debian/copyright as a file that describes the copyright information of software, but the update of this is left to the package maintainer, and there are some packages that are not updated and the contents do not match. Therefore, Debian users may use a tool to check it separately from his file contents. This is too efficient and think that it is not good for Debian itself. We want to update as much as possible and reduce the burden on developers and users. This time, not only us but also the other works are being made, and we summarized the current situation and how to update and keep debian/copyright.

The Debian base image size and features provided are increasing year by year. Therefore, due to its large size for embedded devices and containers, Debian may not be adopted by the system. This time, while following the existing package system, we examined and implemented an image construction method using busybox and mmdebstrap.

In the embedded product development, developers carefully need to select the base system and development tools from various Linux distributions and open source software. Selecting appropriate distro and tools is necessary for efficient product development. Especially in the industrial world, 10+ years maintenance is required, including security fixes, reproducible builds, and continuous system updates. Debian has been applied to industrial products because of its affinity with the demands in such developments. Kazuhiro will introduce several approaches for embedded product development, which are based on Debian sources, binaries, and tools. He also shows the basic usage and preferred use cases of each approach, including the relations between important features in Debian.

When software developers try to apply Linux into their embedded products, they would be able to choose their base system from various distributions today, which could be divided into two kinds; binary based and source code based distributing. Debian, one of the major binary based distributions, has stability and long-term support from its strong communities, which are essential stuff especially for civil infrastructure system. On the other hand, additional efforts for customizations and management of product releases are sometimes needed to cover various product requirements. Kazuhiro will introduce approaches for applying Debian into embedded systems with Yocto Project build tools. In this talk, he will show some possibilities in combining Debian and benefits from Yocto Project, examples of customizations and resource managements, lessens learned from product developments thus far, and future plans for getting better affinity with Debian and other communities.

Cross-building Debian packages is important topic for embedded developers. Many activities are there for cross-building or tooling for that in debian-embedded, debian-cross and others. In this BoF, the following topics would be discussed (and others are welcome) to share the current development state of cross-building, clarify new issues to be solved, and future plan of such kind of activities. * Recent issues in debian-cross * How to share efforts (i.e. patches, testing, investigation) for cross-building packages * Infrastructure for cross-building packages (cross-buildd?) * Involving people who are interested in this topic (info in PTS, etc.) * Documentating using Wiki to share information * And more...
