I got sick of fixing things when I went to do 'emerge update' on my gentoo box, so I changed my ACCEPT_KEYWORDS thinking that if I didn't try to download the 'unstable' versions that things would 'just work', but I was wrong.
So I'm installing debian. So far, it's faring much better than it did the last time I tried it (and I've only had to manually interfere with the installer once to fix the grub configuration).
