Docker container of jetpack-nixos

[sauvejuSICKAG]

Hi, thanks for all your hard work!
Sorry for the newbie question; I've only dabbled with the nix/os stuff other people have setup, but I'm not a proficient user yet.

We currently develop on the nv orin, jetpack 5+, ubuntu, and have encapsulated various build/runtime environments within docker containers (to minimize destroying the host env), built off of nv l4t-base image. The only troublesome aspect, is that the devel container is like 12 GB once all supporting libraries are installed, compiled, etc, even after all the space-saving tricks we know. I remembered that the nix-ification of the ROS system led to like 20% build-times/size, and I'm trying to figure out if I could gain the same benefits using jetpack-nixos.

The problem is, I'm hesitant to "break" my jetson by replacing the ubuntu os, since if I mess something up, I'm not experienced enough to recover well. I'd like to try it out within a docker, but I haven't seen any mention of this use case.

Is it merely as simple as using the nix docker, with the /overlay.nix from this repo?
