And it was you or Neil or someone else here who pointed that out maybe
1-2 years ago so I stopped doing it twice.

But, heck, why not? I do a lot of pointless things every day. I only
do new installs a few times a year... ;-)

Anyway, right after the system first comes up it's usually less than 1

very few _strange_ problems bringing up Gentoo since I started doing
it. (In 2000, so 10 years now...)
