Edit: Curious, why the downvote?

I'm more amazed you run the same machine for 20 years. Another 20+ years user, but I've reinstalled 5-6 times when I change laptops.

No, I changed the machine, but just installed Gentoo every time. I merely kept the emerge.logs from each machine.

> why the downvote?

I can see no reason for it.
