Hello Dan,

Here it is what i've understood about it:

!!! it's right SINCE centos 3.3 (it's not right for a 3.1 systems
upgraded in 3.3 because of an old symbolic link ! ):

- yum RPM put a "/etc/yum.conf" , each time yum RPM is upgraded,
/etc/yum.conf is NOT replaced.

- centos-yumconf put a "/etc/centos-yum.conf" , each time centos-yumconf
RPM is upgraded, "/etc/centos-yum.conf" is *overwritten*.

the necessity of this package (i think ... ) is simply to provide the
proper clean configuration for centos ... who remain in
/etc/centos-yum.conf( which is never used by yum in *3.3* ), while
/etc/yum.conf is an exact copy of it, but this last one is used by yum.
So you never loose the original configuration while you make change into
/etc/yum.conf, in addition of that, don't worry about yum's RPM updates
which *could* be make changes to /etc/yum.conf, it *should* not: changes
are to be made (will be made) in /etc/centos-yum.conf.

He hope it's clear enough :-]
