VPP in VyOS runs under systemd control, and the system’s syslog (including VPP logs) is captured and stored by journald. For an unknown reason, this setup results in all VPP messages being duplicated in journald. ``` vyos@vyos# sudo journalctl -b --unit vpp | tee Nov 19 14:46:07 vyos systemd[1]: Starting vector packet processing engine...
