What is COOL?

COOL - Compact OSADL Online Lectures: Open Source meets Industry

  • COOL is an OSADL webinar series.
  • COOL takes place regularly once a month and covers new and state-of-the-art topics on Open Source software in industry, either on legal or on technical aspects.
  • COOL editions each consist of two lectures covering a special "Open Source meets industry" topic followed by a discussion round. The first "basic" lecture provides basic knowledge with regard to the respective topic and the second "advanced" lecture dives deeper into the topic and highlights special aspects. The discussion round gives all participants the possibility to ask questions and discuss with the respective speakers and the audience.
  • COOL speakers are OSADL experts on the one hand and external specialists on the other hand who kindly agreed to share their expert knowledge on the respective topic.
  • COOL is a virtual event. The lectures are held by live video streams. Speakers will be available for questions and discussion in a video conference which will take part subsequent to the live video streams.
  • COOL in general is designed to provide support how to best and compliantly use Open Source software in industry.

Description COOL October 2024 edition:

In the good old days of the UNIX operating system, the default initial process that is started immediately after booting the kernel (also known as the "init" process) was a simple shell script, usually referred to as BSD-Init. Later, this was extended by the so-called System-V-Init or SYS-V-Init process to separate the script into so-called run levels. Symbolic inks were used to enable or disable the start of a particular program in a selected run level such as single-user, multi-user or graphical user interface. To overcome the disadvantages of this static and sequential way to start a system, event-driven concepts with parallel process execution were introduced - initially upstart, which was eventually replaced by systemd. As there are important differences between the various concepts of init processes, their selection should be well considered – especially when developing embedded systems. Therefore, in the basic lecture of this COOL session, an overview about historic and present concepts of UNIX init processes along with their pros and cons will be given by Jan Altenberg from OSADL.

When the decision was made to modernize the init process in response to the many requests from users and especially maintainers of Linux distributions, it would have been possible either to extend the existing init concept or alternatively to create a completely new concept. As we all know, the latter approach was chosen, and under the leadership of Lennart Pöttering, systemd was created – much praised and much hated at the same time. The main advantage of systemd is best demonstrated in the context of large workstations, for example for office computers. On the other hand, it remains questionable whether systemd offers sufficient advantages in an embedded system to compensate for its size, complexity and possible error-proneness. However, if systemd is configured to use only proven and less intrusive components, it can be very well suited for embedded systems. Michael Olbrich from Pengutronix has gained a lot of expertise and has even become an advocate of systemd for embedded systems; therefore, OSADL is very pleased to announce his contribution in the advanced lecture of this COOL session.

Recommended audience COOL October 2024 edition:

Software architects, software developers, software engineers and system integrators of embedded Linux systems.

About the speakers of the COOL October 2024 edition:
