the aaa_base or similar "base" packages on rpm based
distributions are usually some kind of "fake" package
which gets installed after the "base" installation
required to get rpm, etc working. so these packages
usually list a number of files, but do not contain
any of those files (they usually can be found on the
first installation CD in a directory named "*base*" ...
the installation scripts simply copy the files to the
destination directory/medium and then install the
selected packages including the fake aaa_base package.

hope this helps,
