Wrong permission of /var/virtualization after fresh install

[dev-zero]

Current:

vm-test-02 # ls -la /var/virtualization/
total 12
drwxrws--- 11 root root       4096 24. Dez 15:51 .
drwxr-xr-x 12 root root       4096 24. Dez 11:28 ..

Required:

vm-node-01 # ls -la /var/virtualization/
total 8
drwxrws---  2 root vm-storage 4096 12. Nov 11:50 .
drwxr-xr-x 13 root root       4096 21. Aug 15:07 ..

The predefined-storage.tar.bz2 archive has it correct:

vm-test-02 tmp # mkdir foo
vm-test-02 tmp # tar -xvjpf /usr/share/foss-cloud/predefined-storage.tar.bz2 -C foo/

So there must be a script which resets the permissions at some point
