I’ve been using https://containertoolbx.org/ recently to manage my “other distro” requirements. It doesn’t do anything special but works nicely as a wrapper around podman and does all the bind mounts and uid mappings so you can just enter your $HOME as though you have set up your account in a new OS.
According to the article new builds still can’t use gas boilers so I suppose there is that. Dealing with our existing housing stock is going to be a challenge though. Although I plan to eventually replace the gas boiler I’m not sure what with yet. I don’t think air source heat pumps will be able to warm my stone build Victorian house.
