It’s awesome. The packages don’t matter because you use distro box if there’s not a flatpak that works already. I have an Ubuntu distro box for tools for things that don’t work on fedora.
It uses ublueos for an immutable which is rock solid. Idk how to explain it well, but it’s the only distro I want anymore.
If u do end up trying it and find a package that doesn’t work, ping me and I’ll get you a command you can run to do it
Just use distrobox with Ubuntu or Debian for your tools and such. It tightly integrates with your OS and doesn’t sacrifice the immutability
