[gentoo-user] mini-install-cd: default root password or other idea

[n952162]

I know, of course, this doesn't exist, but why is screen(1) asking for it?

I'm re-installing gentoo.  I booted off the image and ran screen.  Did
everything find, with multiple screens, inclduding for ssh to other
hosts.  I got to the point where I ran emerge-webrsync.  It  taking way
too long, downloading into /mnt/gentoo/var/tmp/gentoo-20201104.* at a
snails pace.  I closed all my other screens.  It kept downloading ...

then, suddenly, the screen was erased (maybe I hit a key?) and I stuck
at the top of the screen with

"Screen used by root on live cd"

"Password:"

Am I going to have to kill the installation and start at least the
webrsync all over?
