In CentOS 5 and 6, I was able to install updates automatically as part of a kickstart installation by specifying the updates repo along with the main CentOS repo, e.g.

repo --name="CentOS"  --baseurl=http://mirror.cs.pitt.edu/centos/6/os/x86_64/
repo --name="CentOS 6 - x86_64 - Updates" --baseurl=http://mirror.cs.pitt.edu/centos/6/updates/x86_64/

This saved a lot of time by not having to do updates separately after the initial installation.  Now, with CentOS 7, I tried to use similar repo lines in the kickstart file.  When I try using that kickstart file, the updates repo fails with this message in packaging.log:

19:22:23,934 DEBUG packaging: adding yum repo CentOS 7 - x86_64 - Updates with baseurl http://mirror.cs.pitt.edu/centos/7/updates/x86_64/ and mirrorlist None
19:22:23,939 DEBUG packaging: retrieving treeinfo from http://mirror.cs.pitt.edu/centos/7/updates/x86_64/ (proxy:  ; sslverify: True)
19:22:23,943 INFO packaging: Error downloading treeinfo: [Errno 14] HTTP Error 404 - Not Found

I checked my CentOS 5 and 6 update repositories and there isn't a treeinfo file in any of them.

Has anyone else seen this?

     Thanks,
