# So upon upgrade, we check if the configuration files are present and we move
# them if the target does not exist. As we provide ucf with historical md5sums,
# ucf should be capable of handling the situation well.
#
# Of course we also need to replace the original softlinks.

#       We only need to do this if the target does not already exists. If the
#       target already exists, we can later call ucf straight as there
#       is already a version of cacti configuration available, althought never
#       provided by this package, but we can just propose the new file anyway.
