verbose is a debugging setting one step noisier than debug and should only be turned on when debugging because it leaks quite some credentials and tokens in the journalctl.
This reverts commit 6af3d13bec.

Does this not completely break the service? It doesn't change the
owner to the same as the ddclient server (which is somewhat difficult
due to it being a DynamicUser), so this now makes the service
completely unusable because the config is only readable by its owner,
root:
ddclient[871397]: WARNING: file /run/ddclient/ddclient.conf: Cannot open file '/run/ddclient/ddclient.conf'. (Permission denied)
Given that the RuntimeDirectory was only readable by the ddclient
service, the warning this PR fixes was spurious and not indicative of
an actual information leak. I'm not sure of what a quick fix would be
due to DynamicUser, but would at least request a revert of this so the
service can work again?
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file
The the extraConfig variable is added below the domain variable in the
ddclient config file. The domain variable should always be last.
(cherry picked from commit ba0ba6dc7934a6b4cc5d4090739a3a1c839afe67)
a) Some providers can update multiple domains - support that.
b) Make "zone" and "script" configurable. Some providers require these.
c) Instead of leaving the ddclient daemon running all the time, use a systemd
timer to kick it off.
d) Don't use a predefined user - run everything via DynamicUser
e) Add documentation
Couple of changes:
- move home to /var/lib/ddclient so we can enable ProtectSystem=full
- do not stick binary into systemPackages as it will only run as a daemon
- run as dedicated user/group
- document why we cannot run as type=forking (output is swallowed)
- secure things by running with ProtectSystem and PrivateTmp
- .pid file goes into /run/ddclient
- let nix create the home directory instead of handling it manually
- make the interval configurable
This avoids the following warning:
Apr 19 10:53:48 xen systemd[1]: [/nix/store/...-unit-ddclient.service/ddclient.service:19] Unknown lvalue 'type' in section 'Service'
As `Type=simple` is the default in systemd, the assignment to the
service type can be simply dropped.
* rewrite to systemd.services
* disable forking to give systemd better control
* verifiably run as ddclient user
* expose ssl option
* unset default value for dyndns server
* rename option "web" to "use" to be consistent with ddclient docs
* add descriptions
* add types to options
* clean up formatting
modprobe.
* Move the implementation of boot.kernelModules from the udev job to
the activation script. This prevents races with the udev job.
* Drop references to the "capability" kernel module, which no longer
exists.
