I'm experiencing the same problem with Fedora 16 x86_64 and ddclient-3.8.0-4.fc15.noarch

I attach a patch that solves the problem.

Sorry for pasting the patch here, I forgot to rename the file as /etc/tmpfiles.d/ddclient.conf

Add /var/run/ddclient directory creation to tmpfiles

Fix previous patch by creating the tmpfiles.d directory in the buildroot

This also affects ddclient in Fedora 16. With the changes to systemd recently, without a proper /etc/tmp.d/ddclient.conf boot hangs.

*** Bug 753714 has been marked as a duplicate of this bug. ***

This is a show stopper.  Took me forever to figure out why my F16 system was hanging on boot.  Any chance of getting at least an updates package with this fix?

I am suffering the same issue with ddclient. Can someone please explain what is the workaround for F16?

I checked and /var/run/client does exist in F16:

drwxr-xr-x. 2 ddclient ddclient 40 Mar  8 00:49 /var/run/ddclient

Yet, I get the same error as described in Bug 753714:

systemd[1]: PID file /var/run/ddclient/ddclient.pid not readable (yet?) after start.
systemd[1]: Unit ddclient.service entered failed state.

I have disabled SELinux to check whether there was a permission problem, but it kept on failing. Running ddclient manually does work properly.

Any clues anyone?

Sorry, I meant to say Bug 781526 in Comment 11.

create /etc/tmpfiles.d/ddclient.conf

containing line

d /var/run/ddclient 0755 ddclient ddclient -

Why can't that file be added to the ddclient package? Who is the ddclient packager?
