metapackages and setting config files in /etc and /home/dir

[Stephan Foley <foley12723@gmail.com>]

Hello, let's say I have the following install:

my_metapackage -> depends on windows_manager -> depends on lightdm ->
depends on xorg

So, I am forcing the following:

- xorg
- lightdm
- windows_manager

can I set the configuration files? For instance, can I set the lightdm
config in /etc or the windows_manager's config in /home/user? Or can
only the original package set this?

Thanks
