which results in
KSRCURL http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.13.1.tar.xz
PURL http://vserver.13thfloor.at/Experimental/patch-3.13.1-vs2.3.6.10.diff
LASTCONFIG /boot/config-3.10.11-vs2.3.6.6+lihas1
* 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:
script -c "kernel-autobuild --kernel-base-version ${REL} " typescript3131
/!\ But ... the new kernel fails here :-( /!\
kvm start fails:

[ 0.464843] No filesystem could mount root, tried:
[ 0.466592] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
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
