Rudder

In the rudder-webapp postinst, the use of the command "git commit -m 'initial commit'" create a file with mode 644, which is the default mode. It leads to an error with ncf post-hook since the previous command create the file 'COMMIT_EDITMSG' :

root@rudder-snapshot:/var/rudder/configuration-repository# tail /var/log/apache2/error.log

To ensure that no other file could be created during the postinst, we should add permissions to group recursively on all .git.
