I haven’t done this for ages on my server. After it died yesterday under the most mysterious of circumstances, I am seriously considering doing an emerge world. I’m just worried that everything will fall apart; especially the qmail installation.
Qmail is now marked as deprecated in portage; replaced by netqmail. Only one way to find out if doing a “udv” will break it or not!!! *backs up emails*
Hopefully demerge actually works.
