Major Description
Currently, Hue creates a new file whenever it needs to update its app registry:
def save(self):
"""Save and write out the registry"""
assert self._initialized, "Registry not yet initialized"
tmp_path = self._reg_path + '.new'
self._write(tmp_path)
os.rename(tmp_path, self._reg_path)
LOG.info('=== Saved registry at %s' % (self._reg_path,))
It should not create a new file, but truncate and overwrite the previous file so that symbolic links are preserved.
