Hi,

prometheus-node-exporter does support socket activation. All it takes is
passing --web.systemd-socket and having a .socket unit. In fact, the
upstream provided systemd examples in examples/systemd/ do exactly that.

The examples cannot be just installed, because they use $OPTIONS instead
of $ARGS and /etc/sys_config instead of /etc/defaults.

Could you copy the socket activation pieces anyway?
