Exactly, ublue and in turn bazzite basically (oversimplification) add their own “layers” on top of fedora silverblue/kinotie, basically doing the same thing you do when using rpm-ostree.
I’m so happy to hear it! I’ll put off searching, for now :). If you do find the answers you should definitely post in this thread, I’m curious and others might find this thread when they encounter the same problems. No problem! I’ve had a lot of help from the community, so just paying it forward!
This documentation is for bazzite, but they have a lot of the same stack under the hood. “Broadcom’s WL driver can be installed since it is needed by some hardware. Disabled by default. Enter “just use-broadcom-wl” to use it.”. You could try to see if aurura has the same “just” options, that’s where I would first research. If not, then yeah, “rpm-ostree” would be how you install the package, just like you said, just not sure of the commands for local files. Also there is a tool to “roll your own” distro built on top of any of the ublue work, it’s basically how bazzite and aurora exist. So you can layer the packages like the other option you said. https://github.com/ublue-os/image-template
