+  * if KSRCURL is not set: major error - either your system can't reach kernel.org or the format of the web page has changed
+  * if PURL is not set: either your system can't reach linux-vserver.org or the format of the web page has changed
+  * if LASTCONFIG is not set: you have to provide one by yourself, e.g. copying one into /var/lib/kernel-autobuild/${REL}/00-resources and using --config /path/config
+so:
+<code>
+    script -c "kernel-autobuild --kernel-base-version ${REL} " typescript3131

+/!\ But ... the new kernel fails here :-( /!\
+kvm start fails:

+</code>
+addendum 2016-10-23:
+* similar looking problem with 3.18. Then, no initrd was built during package installation because the dpkg hooks silently failed to do so. Fixed by using a debian 7 / wheezy test image
+prequel:
