Thinking of trying to morph my Leap workstation into Tumbleweed (and potentially Slowroll once that project matures enough). I’ve seen that you can do it . I reckon I can rollback relatively easily via the BTRFS snapshots if it goes sideways, but just curious to see what others’ experience with doing so has been.
RTFM. The setup of a user-level flatpak is right there in the Wiki: https://en.opensuse.org/Flatpak
Like I said, last time I checked even a “user” level Flatpak required to use the root password to install. But it may have changed (for the better) since, which is a good thing.
Still, my main point is that most the paranoia of the default OpenSUSE settings is way overboard, and should be toned down quite a lot. A lot of action that would ask for the user password, if not no password at all, requires the root password on OpenSUSE.
I want to use OpenSUSE over Ubuntu or Fedora, I even started contributing back with some package updates here and there, but I just can’t because of those bothering root password prompts everywhere.
