Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
Thank you for the warning. This is exactly the kind of thing that makes this not at all just as easy as creating a bootable backup of a Mac! And it’s the kind of thing that makes “this is easy” difficult to take seriously.
Now I know what to search for and I will probably be able to piece it together.
