Oh well, it was a long shot :-)

I don't use ddclient (never heard of it until you posted here) :-)

I think, after a bit of testing it's an issue that can be ignored or
mitigated by changing the ownership of ddclient.conf.

I had a go at installing it on my alpine box, it went on cleanly with a
couple of dependencies.  It also created a ddclient user in /etc/passwd
however /etc/ddclient looks like this :-

OBFUSCATED:/etc/ddclient# ls -al /etc/ddclient/
total 20
drwxr-xr-x  2 ddclient ddclient  4096 Oct 13 07:45 .
drwxr-xr-x 50 root     root      4096 Oct 13 07:45 ..
-rw-------  1 root     root     10224 Nov 24  2023 ddclient.conf
OBFUSCATED:/etc/ddclient# 

note that ddclient.conf is owned by root when installed.

When I run your command :-

OBFUSCATED:/etc/ddclient# ddclient -daemon=0 -debug -verbose -noquiet
=== opt ====
opt{cache}                           : <undefined>
opt{cmd}                             : <undefined>
opt{cmd-skip}                        : <undefined>
...
globals{syslog}                      : 1
globals{verbose}                     : 1
=== config ====
=== cache ====
OBFUSCATED:/etc/ddclient# 

It all seems to work fine.

I changed ownership of /etc/ddclient.conf :-

OBFUSCATED:/etc/ddclient# chown ddclient:ddclient ddclient.conf 
OBFUSCATED:/etc/ddclient# ls -al
total 20
drwxr-xr-x  2 ddclient ddclient  4096 Oct 13 07:45 .
drwxr-xr-x 50 root     root      4096 Oct 13 07:45 ..
-rw-------  1 ddclient ddclient 10224 Nov 24  2023 ddclient.conf
OBFUSCATED:/etc/ddclient# ddclient -daemon=0 -debug -verbose -noquiet
WARNING:  file /etc/ddclient/ddclient.conf: file /etc/ddclient/ddclient.conf should be owned only by ddclient or not be writable.

=== opt ====
opt{cache}                           : <undefined>
opt{cmd}                             : <undefined>
opt{cmd-skip}                        : <undefined>
...
globals{syslog}                      : 1
globals{verbose}                     : 1
=== config ====
=== cache ====

so it seems that the warning is only issued if the file is owned by the ddclient user.

I also got an email with the warning in :-) :-
