dpkg-divert

[rosea grammostola]

Hi,

I made a custom package to customize the Gnome2 menus. When I install the
package I get the warning:
 trying to overwrite '/etc/xdg/menus/applications.menu', which is also in
package gnome-menus 0:2.30.0-0ubuntu4

To fix this I was looking into dpkg-divert, but it didn't became clear to me
how this actually works and how I should use it.

The existing applications.menu file (gnome-menu package) should be renamed
to something like applications.menu_bak right?

This is what I have in the preinst file right now:

dpkg-divert --divert /etc/xdg/menus/applications.menu_gnome --rename
/etc/xdg/menus/applications.menu

But it gives:

(Reading database ... 141750 files and directories currently installed.)
Unpacking openstudiomenu (from .../openstudiomenu_0.1-1ubuntu1_i386.deb) ...
Adding `local diversion of /etc/xdg/menus/applications.menu to

Another thing I would like to know is how to make upgrades to new versions
of the package run ok?

Thanks in advance,
