[ale] SUCCESSFUL: Add source repo to CentOS, Was: Epic 'wish I had chosen Debian' fail

[Richard Bronosky]

My repos list included the following "base" entry:
[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

I discovered the if you use your browser to visit the baseurl which is
commented out, you can navigate back out of the architecture directory
and find the SRPMS directory. Using this I created the following
"base-source" entry:
[base-source]
name=CentOS-$releasever - Base - Source
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://mirror.centos.org/centos/5/os/SRPMS/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

Now I can successfully do "yumdownloader --source" commands. From what
I can tell this is either non-documented or completely Google-proof. I
did try every combo of &arch=(source|src|srpm|SRPM) and
repo=os-(source|src|srpm|SRPM) but the CentOS mirror list seems to not
have any source repos in it.
