We had a look at this during the Paris BSP.  Below is a summary of the
issues.

In the wheezy version:
- /etc/mcollective/server.cfg is not shipped in the package, but is
  copied from a template in /usr and modified according to debconf
  answers by postinst
- /etc/default/mcollective is shipped as a conffile *and* modified
  according to debconf answers by postinst

In the jessie version, /etc/mcollective/server.cfg is shipped as a
conffile, thus conflicting with the earlier postinst-generated version;
/etc/default/mcollective comes as a conffile and is left alone.

The easiest way to "fix" this for jessie is to remove mcollective from
the distribution; another option would be to stop installing
/etc/mcollective/server.cfg in the package (it still gets installed by
postinst if it's missing anyway).

Cheers,
Julien
