The `collectd-version` script uses the *collectd* UNIX socket to send
custom values to *collectd* to track the OS version. Since these values
obviously cannot change while the system is running, the values are
specified with a very long interval. This avoids having to continuously
insert the values, either with a long-running process or by repeatedly
running a script. The values only need to be inserted once when
*collectd* starts.
