+obs-service-kiwi_label_helper
+=============================
+
+This service can be enabled to run during buildtime, when it will edit the
+kiwi image descriptions to expand the <suse_label_helper:add_prefix/\>
+element.
+
+Example:
+
+```
+<image [...] xmlns:suse_label_helper="com.suse.label_helper">
+[...]
+       <containerconfig [...]>
+         <labels>
+          <suse_label_helper:add_prefix prefix="com.suse.sle.base">
+            <label name="org.opencontainers.title" value="SUSE Linux Enterprise Server 12 SP3 Base Container"/>
+          </suse_label_helper:add_prefix>
+```
+
+expands to
+
+```
+<image [...] xmlns:suse_label_helper="com.suse.label_helper">
+[...]
+       <containerconfig [...]>
+         <labels>
+           <label name="org.opencontainers.title" value="SUSE Linux Enterprise Server 12 SP3 Base Container"/>
+           <label name="com.suse.sle.base.title" value="SUSE Linux Enterprise Server 12 SP3 Base Container"/>

+- Do not ever use "%setup -n .": rpm 4.18 tries to be cleaner and
+  remove stuff it extraced, which would lead to 'rm -rf .', which
+  rm does not like. Use "%setup -c" instead, which creates the
+  appropriate %{name}-%{version} directory expected.
