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.
Don't do it. Instead of doing something useful you will be in a constant process of updating and rebooting and dealing with breaking changes and eventually you will give up and switch back to Leap.
I have used TW for years, and never got bothered by a breaking change for more than a day. And that only happened twice.
The only thing that keeps bothering me with Opensuse is their obsession with asking for a root password (and not for yours if you are an administrator, I mean the root user password) for every damn thing. Even installing a fucking user Flatpak requires a fucking root password !
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.
