This is interesting to me for my use case scenario, specifically SteamOS.
What I’m trying to do is run an emulated Everquest server (lookup EQEmu). The community there has several methods of installation of the server, Windows, Linux, and Docker. The hurdle to overcome is the immutable file system, specifically when it comes to the database (MariaDB). I think I may have found a work around via Linux brew and installing MariaDB through that (which I’ve done, I just have to make the final connection). However the Docker setup, when running it on a separate distro is stupid easy. If they make this a Flatpak, it can potentially be the solution I’m looking for.
Really the end goal is creating a Single player Everquest. I have a dual boot with it operating via Windows, but would much prefer to have it on the SteamOS side of the house.
