If I have a problem, I try (and with Linux) often succeed to understand the problem. This is very rewarding and allows my systems to run without many problems, since I can extinguis issues at the cause.

That’s the simplest answer.

Shouldn’t everyone that installed Arch the right way be able to do it on most distros, simply after installing Pacman?

Though I think changing (shrink, create new, migrate, delete old) the partition layout would count as installing another distro on top…

Want a challange? Start with something like Silverblue.

Do you have sources on the “burn out” phenomenon?

As far as I’m aware there’s stress buildup from thermal cycles and overheating - but now burn out from keeping the hardware at, let’s say 95C.
