I looked over the patch and tried it out briefly, and I'm ok with it 
too. As mentioned previously, I'm no expert on the security 
implications, but this does resolve my (perhaps slightly paranoid) 
concern about symlink attacks.

Hopefully we can come up with a longer term solution that makes it 
easier for Gentoo users to get things set up correctly, but I'm not sure 
off-hand what the best strategy there would be...
