I had a Casio remote control watch that I was actually using all the time in my room. I used it in an evil way only once, since the TV sales guy was showing off how loud the super high-end TV is. As he turned the volume up with a maniacal smile, I just pressed OFF button. New money couple lost interest immediately.
It is Casio CMD-40 for the interested.
It was a serious issue back then. People were wandering around on the Internet with root accounts. A lot of #linux IRC channels were kicking&banning anyone with "~root" or "root" ident with educational sentence like "Do not use root account as your ordinary account, check instructions". We don't see the issue widespread today since distros did very good intended "dark patterns" to push users to regular user accounts. Linux (or UNIX) "root" account is true god mode. E.g. infamous "rm" as root joke (!) could even affect Windows running WSL2, so MS had to implement special workarounds.
It is all about private "dinners".
It will be isolated in its own directory, as I said I think distrobox.it+neon+, own home will be a far better solution of course. I keep hearing Flatpak is adding snap-like deeper features so I wondered how far it went. About the KDE 6 being unstable: I think they wanted to ship something out and for people preferring stability, 5.x LTS will be there for a long time.
I mean as you can use far newer KDE applications on Debian stable via Flatpak, it may serve the same purpose contained in a separate tree without changing the core OS.
I guess distrobox+neon would work fine yes. I just wondered the state of Flatpak with the recent changes.
I understand it won't be trivial but I wonder if, theoretically, a team can ship & maintain a KDE 6 "flatpak" or "snap"
I mean in technical terms, not that they would with the non technical mistakes Ubuntu keeps doing.
Really weird thing is, distros and flathub kinda pushes users to do system wide installs while most of the packages can work and get updated per user. They are pushing the thing which made Windows almost impossible to use without an administrator user. A dramatic example would be gnu guix, almost never requires root for updates or installs. It is also usable by normal users. From GNU... :-)
First of all you can check distrobox.it which can basically run Neon inside your distribution however you better set a different virtual home for neon in that case.
I would first tar the .steam to be on the safe side but steam is different, it is some kind of Ubuntu stable itself residing in that directory. Not a big time gamer but people laughed at Ubuntu for shipping its snap because of it.
Long story short I don't think steam would have issues. I meant not to expect KDE guys to revert upgraded preferences back to KDE5 etc. You know they do such things and blame Linux/KDE etc.
If you use a rolling/half rolling release like Tumbleweed/Fedora, Nouveau is pretty usable and it progresses. That is unless you are a gamer or do AI stuff. It is Nvidia who had to provide an open source driver to their customers. I don't think Nvidia customers figure they are customers, not beggars as they don't demand it. That even includes governments and the military.
A separate /home can save you hours or even days in several occasions however don't try crazy things like trying to have KDE of Ubuntu share same theme/settings with KDE6. A /var on a fast drive can create wonders too.
I refuse to answer such a stupid question.
