Busybox syslog uses a shmmem circular buffer [1][2] when launch with -C option
when systemd (is enabled) takes the control of syslog messages and then forward
the messages to busybox syslog daemon, systemd journald don't usage of shmmem
circular buffer.
If -C is specified busybox-syslog never be able to read the forwarded
messages from systemd journald and don't wrote it to /var/log/messages.
This file is only installed when systemd is enabled [3].
