FC7 to FC8 Upgrade - fc8 needs 8KB ?

[Jim Duda <jim@xxxxxxxxxxxx>]

I'm trying to upgrade from FC7 to FC8 via Yum.

After dependencies are resolved and download occurs, the update starts, 
but fails with these messages:

  installing package fedora-release-8-5 needs 8KB on the / filesystem
  installing package perl-XML-SAX-0.16-2.fc8 needs 8KB on the / filesystem
  installing package xorg-x11-drv-tek4957-1.1.0-4.fc8 needs 8KB on the 
/ filesystem

filesystem
  installing package glx-utils-7.0.2-3.fc8 needs 8KB on the / filesystem
  installing package rpm-python-4.4.2.2-7.fc8 needs 8KB on the / filesystem

Error Summary

Can anyone explain what needs 8KB on / filesystem means?

Thanks,

Jim
