Ensure system journal files are group-owned by systemd-journal

journal-files-group · UBUNTU ≥ 22 · 1 impl

Description

All files under /run/log/journal and /var/log/journal must be group-owned by systemd-journal, the group systemd grants controlled journal access to.

Rationale

Journal files group-owned by an unexpected group could be edited or deleted by members of that group, destroying or falsifying the operational and security record the journal is meant to preserve.
