Well idk what Fedora’s Toolbox or Podman are, but from reading what you want Haiku to do, I think this is related to what I’m trying to solve myself Can Haiku boot from itself (i.e. it’s own image)? and with everything else I’ve been working on, I haven’t had time to mess with it beyond what I did. But I plan to get to it in a few weeks for fun, and see if it works… from what I read it sounds like Haiku doesn’t have imaged environments.
I guess what Haiku does have is the ability to go back to another system state from its boot menu, so its possible to revert from installed packages.
But beyond that, yeah, being able to switch between different instances is missing and as a nerd that has fun with different systems, this really useful feature is missing in Haiku and it feels like me going outside with no socks or shoes on, it’s weird for sure not having it
