We appreciate all feedback, including RFE's and bug notifications.

Notes:

1. Since there are no 32bit packages included in this CD, the resulting install will be 64bit clean.

2. The included packages are a subset of all packages available in the CentOS distribution, however yum has been pre-configured to use the entire repository.

3. In order to ensure that drivers and other third party apps maintain compatibility, the package set used on the Server CD is from Release time CentOS 4.7, you are strongly encouraged to run a 'yum update' immediately after installation.

4. As some of you will notice, the iso size is lower than the 650mb acceptable for a single CD. Feedback on what other packages should be aded or removed from this Single CD for the next release are very welcome."
