+ SIGUSR2

+ Upon reception of the SIGUSR2 process signal systemd-resolved will flush all
+ caches it maintains. Note that it should normally not be necessary to request this explicitly – except for
+ debugging purposes – as systemd-resolved flushes the caches automatically anyway any time
+ the host's network configuration changes.
