I would attribute a stable Gentoo system to skill and patience, not luck.

Out of curiosity, what is your use case for this particular Gentoo install? 15+ years is a long time to keep the same machine running.

This particular one is my general purpose desktop. I use it for everything from Emacs, development, web browsing, games (Steam mostly) etc.

Physically there is nothing left of the original hardware as it has gone through many generations of part replacements, Ship of Theseus style. It's the OS image that has survived through all this. My /home which I keep separate is another 10 years older.

Could be multiple machines. I carried an image over three laptops, rebuilding with the new `-march` as I went along.

Yeah, that's basically it but I use conservative CFLAGS, pretty much just "-O2" so no need to rebuild for CPU changes.
