I might have misread this, but isn't it policy that Gentoo doesn't
support upgrades of systems more than a year old?

I think it was said that if you go a year without updating, you aren't
supported anymore and you need to just do a fresh install.

Does anyone have any commentary on this?  Even to tell me that I'm mistaken?
