I think this version was compiled without systemd support. This means we
don't use the notify socket and hence systemd will consider the service
not started after TimeoutSec/TimeoutStartSec (90 seconds by default, see
the DefaultTimeoutStartSec in your /etc/systemd/system.conf for the
configured number). Please install systemd-devel and configure will
detect this (or force its use with --enable-systemd).

On systemd machines we prefer to run as a Type=notify service to ensure
the service manager can be sure we started correctly.
