However, this should be added only for version that support it (I guess 5.7.1, but I couldn't find where it was introduced)

Ok, I will search for the right version before to add a workaround

The changelog of rsyslog does not indicate when imuxsock module has been added (it seems to exist since the first versions) but the parameter to workaround this bug has been added since 5.7.1:

From http://www.rsyslog.com/changelog-for-5-7-1-v5-devel/ :

added new config statements

    $InputUnixListenSocketUsePIDFromSystem
    $SystemLogUsePIDFromSystem
    $SystemLogRateLimitInterval
    [...]

I'm not sure on how to check the version of rsyslog with CFEngine.

On shell these commands are OK:

rpm -qi rsyslog | grep 'Version' | awk '{print $3}'

dpkg -l | grep 'rsyslog ' | awk '{print $3}'

dpkg -s rsyslog | grep 'Version' | awk '{print $2}'

But I don't see how to ensure that they are not more recent than 5.7.1

Another solution could be to check the OS version and Service Pack since rsyslog in a OS version or Service Pack should not make major upgrade.

Another method suggested by Nicolas is to use CFEngine to install rsyslog =< 5.7.1 in WarnOnly to throw classes and use them to add the configuration in rsyslog or not.

WarnOnly doesn't seem to work with packages promises... Then I will make a module instead.

A module containing something like:

#!/bin/bash
set -e

TARGET_VER='5.7.1'
LOCAL_RPM_VER=`rpm -qi rsyslog | grep 'Version' | awk '{print $3}'`
LOCAL_DPKG_VER=`dpkg -s rsyslog | grep 'Version' | awk '{print $2}'`

for LOCAL_VER in $LOCAL_RPM_VER $LOCAL_DPKG_VER
do
  if [ "$LOCAL_VER" \> "$TARGET_VER" ];then
    echo "+rsyslog_not_older_than_5_7_1" 
  else
    echo "+rsyslog_older_than_5_7_1" 
  fi
done

Should be called to know if the configuration line has to be added.
