[CentOS] Updating my install directory

Maybe YAM is the 'only' way to do this, and if so, well then its got to wait a while....

Situation: Right now the only usable disk space to locate the install CD files for an FTP/HTTP install is a Win2000 server. Accessed via FTP/HTTP.

So when I do an install from it, I then need to do a yum update and it takes quite some time.

At some point in the next quarter, I will be stable with Centos and my install will move to a Centos server and I guess then I would use YAM.

Is there something I can download from one of the mirrors to bring this directory fairly up to date?
