It’s a bit of an unpopular opinion, but if you pick a mainstream distro there isn’t a lot of difference between them. Especially to somebody who is new to linux.
With most any distro you can use KDE, gnome and other desktop environments. You can pick which one you want to use when you login. So don’t think you’re tying yourself to KDE if you install kubuntu or something.
If you want an easy way to switch to a new distro make sure you create a separate partition for /home. Then if/when you want to install something new you can have it overwrite everything except your home directory. So all your steam configs and games will be left untouched (for example). Alternatively just backup /home somewhere and restore as you need.
They may have been, things were far more trusting back then.
X servers, for example, would accept any connections. So we would often “export DISPLAY=friendscomputer:0.0” in the computer lab and then open windows of embarrassing content. Which at the time would likely be ASCII art…
SSH is used to connect. Ownership, symlinks, etc. are preserved. Add more “excludes” to filter out more directories. Do your first run without " delete" to make sure things are going where you want.
If you want “backups” I would suggest something more sophisticated. But for just cloning this is the way.
It’s only really an option for GUI applications which I intend to launch from a GUI which is a real turn-off as a long-time CLI user. I often want to run something like gimp file.ext from the CLI but can’t (easily) with a flatpak.
I also find the permission system gets in the way quite frequently as well. Like I was using some graphics program from a flatpak (I forget which - rawtherapee or maybe digikam) and it could only see certain directories. I get the security restrictions but it was a bit of hoop-jumping to try to figure out how to get that to stop, and in the end I just installed the snap…
The main reason the original trilogy was so successful is because they were very well made movies made in a time when well made movies hadn’t even been done yet.
