I never quite understood why that wasn't designed in from the start. It
always had the assumption that all repositories were coordinated (or
forced the end user to know more than was usually possible to know about
them), when from the beginning the base repositories involved had
policies that guaranteed that uncoordinated 3rd party repositories would
always be a necessity. The new rpmforge layout helps somewhat, but I've
pretty much had to keep all 3rd party repos disabled and explicitly
enable them with the command line switch just to install/update single
packages.
And while I'm ranting about yum, there has to be a way to pick a
repository mirror that doesn't load your caching proxy with a copy of
every file from every mirror. Since at least Centos 5 the mirrors are
insanely fast so it really doesn't matter any more, but it still doesn't
make much sense to make the mirrors do the extra work.
