[gentoo-dev] emerge --world update

[Ric Messier]

Hi,
        Important question. Where is the information for a --world
update gathered. I had initially emerge'd dev-lang/jdk which installed
the blackdown Java. As I have an irrational preference for Sun's JDK, I
unmerged blackdown and installed Sun's java. However, now when I do a
--world update, I see it trying to install blackdown again. I removed
the blackdown directory (that an unmerge apparently didn't) in both /opt
and /var/db/pkg/dev-java. Is there a database somewhere that I'm not
seeing where I can remove blackdown (and others I've unmerged) so I
don't unwittingly restore packages I've yanked?

Thanks,
Ric
