Almost looks good to me.

Just small nits.

May I ask two coding style changes?

  - Please add spaces around the pipe operator '|'
  - Move 'then' to the end of the previous line, for style consistency

i.e. like follows:

if echo $email | grep -q '<.*>'; then






> +       maintainer=$email
>  else
> -       name="Anonymous"
> +       # or construct the maintainer string
> +       user=${KBUILD_BUILD_USER-$(id -nu)}
> +       name=${DEBFULLNAME-$user}
> +       if [ -n "$email" ]; then
> +               maintainer="$name <$email>"
> +       else
> +               buildhost=${KBUILD_BUILD_HOST-$(hostname -f 2>/dev/null || hostname)}
> +               maintainer="$name <$user@$buildhost>"
> +       fi
>  fi


I think the else-block can be a bit shorter
if you write like follows:


    # or construct the maintainer string
    user=${KBUILD_BUILD_USER-$(id -nu)}
    name=${DEBFULLNAME-$user}
    if [ -z "$email" ]; then
            buildhost=${KBUILD_BUILD_HOST-$(hostname -f 2>/dev/null ||
hostname)}
            email=$user@$buildhost
    fi
    maintainer="$name <$email>"
