It might even be a better idea to implement this from the Android front-end
-that would mean less playing around with the Ubuntu install, making it
more united, and requiring less hacked-together solutions.

For example, it could be done via a symlink: have the config in, lets say,
/system/etc/ubuntu/configs/. Upon installing the preinstalled Ubuntu image,
just look for [$ro.device.name].conf in /system/etc/ubuntu/configs/, and if
found, symlink, then move on.

This way it requires one small change on the Ubuntu side, while providing a
more generic way to store the configs within the device-specific
"container".

What makes me write this are the hacky solutions I've seen around: some
requires a third zip flashed after install, some use a service-ified
shellscript to copy it from the system, and so on.

With the symlink (or any other method what stores the config out of
/data/ubuntu), we cut some minimal files out of the chroot, yet every
device can easily provide their own configs without hassle.
