N:
N: The maintainer script doesn't seem to contain any code other than
N: comments and boilerplate (set -e, exit statements, and the case
N: statement to parse options). While this is harmless in most cases, it is
N: probably not what you wanted, may mean the package will leave
N: unnecessary files behind until purged, and may even lead to problems in
N: rare situations where dpkg would fail if no maintainer script was
N: present.
N:
N: If the package currently doesn't need to do anything in this maintainer
N: script, it shouldn't be included in the package.
