The SUSE packaging of watchman ships a systemd service and socket unit that
can be used for running a system wide per-user instance of watchman via
systemd. To do so you need to execute the following commands as root:
TARGETUSER=myuser
systemctl enable watchman@${TARGETUSER}.socket
systemctl enable watchman@${TARGETUSER}.service
systemctl start watchman@${TARGETUSER}.socket
After doing so any `watchman` invocations you perform as `$USER` should talk
to the systemd controlled instance of watchman.
