commit 5231100d66415a55bc7c1684b2b2ebab4912e53f
Author: Otavio Salvador <otavio at ossystems.com.br>

Really duplicate the disk instead of readd every partition
To avoid possible differences between the original disk layout and the
duplicated one, a raw copy is done. Has been identified a case[1]
where extended partitions had their positions changed due this.
1. http://bugs.debian.org/294520
The recipe[2] to reproduce the problem, on the provided URI, has been
used to produced a test and hence be sure it's not forgotten anymore.
2. http://bugs.debian.org/294520#34
The fix has been produced by Samuel Thibault <samuel.thibault at ens-lyon.org>
(cherry picked from commit 7baa9261b8648840b0d615ceaafcd473e9495dab)
