Distro agnostic packaging

[a-crate]

This is a bit of a legacy issue I suppose, because you're potentially moving away from launchpad, but the source tarballs there don't contain the gsettings override file because it's part of the debian/ directory so it gets treated as part of the metadata for debian packages and not source code.
This works fine for debian and anyone unpacking .deb files, but it means the source tarball is incomplete. Here's the contents of what I get from launchpad:

regolith-default-settings
└── usr
    └── share
        └── applications
            ├── logout.desktop
            ├── reboot.desktop
            └── shutdown.desktop
regolith-default-settings_1.0.8.orig.tar.gz

A temporary (and bad) workaround would be to just have 2 files and update them concurrently. Is it possible to keep this file in the root of the repository and add dh_installgsettings regolith-default-settings.gsettings-override to the install script? I don't know a ton about deb packaging so I am not sure what options there are.
