systemd-journald check the cgroup id to support rate limit option for every messages. so journald should be available to access cgroup node in each process send messages to journald. In system using SMACK, cgroup node in proc is assigned execute label as each process's execute label. so if journald don't want to denied for every process, journald should have all of access rule for all process's label. It's too heavy. so we could give special smack label for journald te get all accesses's permission. '^' label. When assign '^' execute smack label to systemd-journald, systemd-journald need to add CAP_MAC_OVERRIDE capability to get that smack privilege.
so I want to notice this information and set default capability to journald whether system use SMACK or not.
