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

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

Description

All directories 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 directories group-owned by an unexpected group could let members of that group remove or replace journal files, destroying or falsifying the operational and security record the journal is meant to preserve.
