I can confirm that the issue is fixed on today's rolling release!

I'm not comfortable posting my config here for ever but I've uploaded it to ubuntu pastebin and set it to expire in a week: https://paste.ubuntu.com/p/BW5KxyjPQr/

Still seems to be broken on 1.4-rolling-202203270930

Just chiming back in to let you guys know I installed the latest vyos rolling release after all this time and the issue seems to have been fixed!

@SrividyaA I just upgraded to the latest rolling image (1.3-rolling-202007311330) and I can still reproduce the exact same issue with the config above. Here's output from show log.

This happens when the system starts up:

Upgraded to 1.3-rolling-201911041446 and the config file issue is still present.

The ddclient config file got moved to /etc/ddclient/ddclient.conf but ddclient is still trying to load /etc/ddclient.conf in the latest VyOS 1.3 rolling image.

Ok, this is fixed already but I didn't notice because it is not yet merged in the Equuleus branch which I am running.

It is currently impossible to update zones on cloudflare dns via ddclient because the generated configs for cloudflare are mising a zone=<domain.tld> directive.
I also note that the comment for each entry also says "DynDNS provider configuration" regardless of the provider used.
