oneiric: cinder fails due to targets configuration

If you install DevStack on the top of an oneiric, volume operations will fail. It is happening, because oneiric is not using the conf.d approach for targets:

stack@DevStackOSDomU:~$ cat /etc/*-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.10
DISTRIB_CODENAME=oneiric
DISTRIB_DESCRIPTION="Ubuntu 11.10"

stack@DevStackOSDomU:~$ ls -la /etc/tgt/
total 12
drwxr-xr-x 2 root root 4096 2012-09-03 14:02 .
drwxr-xr-x 95 root root 4096 2012-09-03 14:09 ..
-rw-r--r-- 1 root root 103 2011-08-08 09:10 targets.conf

Note: There is not conf.d directory!

stack@DevStackOSDomU:~$ cat /etc/tgt/targets.conf
# Empty targets configuration file -- please see the package
# documentation directory for an example.

Note: No inclusion of /etc/tgt/conf.d (of course)

BUT: cinder expects the conf.d approach!

The exercise.sh shows this error, but stack.sh is not failing:
...
