always fails at boot time with the message status=2/INVALIDARGUMENT
Here is an extract from the system log (a fuller extract is attached):
Mar 18 07:57:56 OaklandWeather.localdomain systemd[1]: Started noip-
duc.service - No-IP Dynamic Update Client.
Mar 18 07:57:58 OaklandWeather.localdomain systemd[1]: noip-duc.service:
Main process exited, code=exited, status=2/INVALIDARGUMENT
Mar 18 07:57:58 OaklandWeather.localdomain systemd[1]: noip-duc.service:

duc.service - No-IP Dynamic Update Client.
Mar 18 07:57:58 OaklandWeather.localdomain systemd[1]: Started noip-
duc.service - No-IP Dynamic Update Client.
Mar 18 07:57:58 OaklandWeather.localdomain systemd[1]: noip-duc.service:
Main process exited, code=exited, status=2/INVALIDARGUMENT
Mar 18 07:57:58 OaklandWeather.localdomain systemd[1]: noip-duc.service:
Failed with result 'exit-code'.
Mar 18 07:57:58 OaklandWeather.localdomain systemd[1]: noip-duc.service:
Scheduled restart job, restart counter is at 2.
However if the unit is started from the console after the boot process
is complete:
$ systemctrl start noip-duc.service
it succeeds.
How can I find out what the argument is with which systemd is invoking
noip-duc, so I can understand why it is invalid at boot time but valid
when the unit is started afterwards from the console? I would simply
recompile it to output this, but noip-duc is written in the rust
programming language, which I to lazy to learn for this one application.
