I second this approach. When rescuing a Gentoo system, my first step would
be to deselect any and every non-critical package from @world, then try to
get @system updated through any means necessary. In the past, I've removed
packages instead of deselecting them, but I've had cases where depclean
refused to do anything because there were already dependency problems, and
sometimes it's hard to know what's safe to unmerge with "-C".
