minimized system: `man` returns exit code 0

[Gareth Davidson]

In a minimized Docker container, the man command is a script that needs an `exit 1` at the end:

Steps:

    docker run -it ubuntu:latest bash

    man somecommand
    echo $?

Expected result:

1

Actual result:

0

[Simon Poirier (simpoir)]

Not a bug in man-db. This is purely related to minimized images and the fact that man pages are not installed, and that the man command diverted by livecd-rootfs.
