Couldn’t find the project in my browser history or Lemmy saves. I’m pretty sure it was Lemmy though that led me to find a GitHub project similar to OSTree. It sounded like it was maintained by one person and it hasn’t been updated in a long time because the author thought it was “done” and they used it frequently.
It was a tool that let them basically create images that could be booted from and it was easy to layer software on top of a base image and I think there were config files similar to Containerfiles but didn’t look the same. Don’t think it be was “goldboot” either but that might be a little closer to what the project does. I don’t think it was something Fedora specific either like bootc.
Update: Found it! It was in the history of a laptop I rarely use (of course). The project is https://github.com/godarch/darch and it does appear to be those things I said: layered, docker-like, bare metal, and OS agnostic.
I don’t suppose you’re thinking of the system BlendOS uses, right? It’s the closest I can think of based on your description but it doesn’t seem to fit the timeframe.
I’m going to assume it’s not Universal Blue… But parts of your description reminded me of it.
Could’ve been something Fedora-ish but based on the GitHub I don’t think that’s it. The most distinct thing I remember is that it appeared abandoned but the author just didn’t feel it needed any changes.
I use like four different devices to browse and some have multiple browsers so checking history has been rough.
Are you maybe thinking of https://distr1.org/ made by the i3 guy?
Interesting but not what I was thinking of. I think in the GitHub also the author gave a specific example of an OS layered with the Steam client.
