Launching screen as a non-root user does not work, because /var/run/screen does not exist, and the user does not have permissions to create that directory.
What are you talking about? Is this about the install-cd (what version), a stage (what date) or something else? There is no 2012.1 CD or profile on Gentoo.

Then this is about the DVD and not about the minimal install CD.
Yes. I tried to make that clear in the bug subject line.
Erp. My apologies. I *thought* I'd made that clear somewhere, saw the subject line, didn't see that it'd been changed.
this is fixed in latest livedvd.
