Why not have it as a separate project? They are tightly integrated. The journal can run very early at boot, where very little else runs and integrates closely with systemd for that. Also, systemd itself generates a lot of events for it, and queries it too when necessary, for example in the "systemctl status" output. The journal is implicitly augmented with systemd-specific data, for example with fields declaring which systemd service is logging. Journald also is responsible for handling stdout/stderr of all running services, and for that is a dependency of the systemd process spawning logic. Hence journald depends on systemd, and systemd on journald, and separating makes no sense. In other words: systemd and journald are separate enough from each other to make them two processes, but way too integrated to separate them from each other entirely and allow one running without the other. > The init system and logging have always been two different things. Yes, but this is hardly a reason to keep it that way. We have good technical reasons to integrate them. I believe logging is an absolutely essential part of service supervision. As such I believe no service supervisor could ever be complete without tight integration with the logging framework.
