Understanding # 13

As systemd isn't actually one giant blob, it's made up of tons of smaller parts, it talks amongst itself as well with other applications via dbus.

dbus is an IPC, InterProcess Communication, device. You can run a 'busctl' to see everything currently connected to the bus.

This is why you NEVER restart dbus as then everything has to manually reconnect to the bus and a vast majority of applications don't know to reconnect. systemd has mechanisms to reconnect though.

@ozoned This was an informative series of posts on systemd, thanks for the effort.

@baldrick Anytime. I'm planning on adding more information as well. Just need some time and energy. :-D If you have questions or would like to know more on something specific don't hesitate to let me know.
