We use Ubuntu at work and I will need to make the same configuration changes to many systems so I am packaging these. One of the configuration changes I need to make is setting lightdm to autologin. For me to package this change it seems I will need to clobber the existing /etc/lightdm/lightdm.conf and replace it with the my customized lightdm.conf. This seems like a bad idea.
How can I do this in a way that is won't cause breakage and is inline with how the rest of the community is working?
