Ergh, this is a bit of fud I fear :(

 -C     Tells  yum  to  run  entirely  from cache - does not download
        or update any headers unless it has to  to  perform  the
        requested action.

              Implemented so you could know if your machine  had  any
              updates that  needed  to  be  applied  without running it
              Returns exit value of 100 if there are packages available
              for an update.  Also  returns  a list of the pkgs to be
              updated in list format. Returns 0 and no packages are
              available for update.

If you run "chkconfig --level 345 yum on" this will configure your
system to run nightly updates, which in turn will also update the
headers, so when you come to running yum during the day it shouldn't
have to download new headers, apart from the ones released that day (or
of course you can just use the -C option.

Again this is not necessarily true, for the base packages (other repo's
it is the case).

I would think for a workstation/desktop install it may be a good idea
for these to be installed and configured at boot, and may be nice if the
other repo's created their own rpm's for the above two, and had it in
their FAQ, but I'm fairly certain that most people would still complain.
