Usage: %1!s! [[state=]enabled|disabled] [[maxdadattempts=]]              [[maxvalidlifetime=]]              [[maxpreferredlifetime=]]              [[regeneratetime=]]              [[maxrandomtime=]] [[randomtime=]]              [[store=]active|persistent]  Parameters:         Tag                    Value        state                - Whether temporary addresses are enabled.        maxdadattempts       - Duplicate address detection attempts.                               The default value is 5.        maxvalidlifetime     - Maximum lifetime over which an temporary                               address is valid.  The default value is 7d                               (seven days).        maxpreferredlifetime - Maximum lifetime over which an temporary                               is preferred.  The default value is 1d                               (one day).        regeneratetime       - Time prior to deprecating an temporary                               address when a new address is generated.                               The default value is 5s (five seconds).        maxrandomtime        - Upper bound to use when computing a random                               delay at startup time.  The default value is                               10m (ten minutes).        randomtime           - Actual time value to use, rather than a                               value generated at boot.        store                - One of the following values:                               active: Change only lasts until next boot.                               persistent: Change is persistent (default).  Remarks: Modifies parameters related to temporary address generation.          If randomtime is specified, the maxrandomtime value is not          used.  Time values can be expressed in days, hours, minutes,          and seconds; e.g. 1d2h3m4s.
