Changes from the old yum-conf

* The files /etc/yum.conf and /etc/cron.daily/yum.cron are not marked
as 'noreplace'. This means that if you have modified /etc/yum.conf or
/etc/cron.daily/yum.cron, your version will be saved as *.rpmsave and
the new version will be put in it's place.

* All the /etc/yum.conf.* files have been removed except yum.conf.309,
yum.conf.30x, and yum.conf.flash

* The yum.conf entries are pointing at /linux/scientific/obsolete/30*,
except for the errata area of /linux/scientific/309/ .

* The yum.cron (/etc/cron.daily/yum.cron) is the yum.cron from
yum-conf-309. It does not point to 309, but has the following changes.

  - The yum.cron uses your /etc/yum.conf. If your
    /etc/yum.conf has an excludes line already in it, it
    adds the entries in /etc/yum.d/yum.cron.excludes. If
    your /etc/yum.conf does not have an excludes line, it
    adds one, with the entries from /etc/yum.cron.excludes -
    It does not use /etc/yum.d/yum.cron.primary or
    /etc/yum.d/yum.cron.secondary. You need to put the list
    of yum repositories you want yum to go to in
    /etc/yum.conf
