I just tried an install from my local repo (boot from CD 1, use http method), and it failed right after entering the root password setting with: Unable to read group information from repositories. This is a problem with the generation of your install tree. Reboot So now what? Is there something I can just extract from the isos? (remember I did that rsync). Is this caused by running createrepo after I copied the CDs, and before I did the rsync -r (so perhaps my tree info files are newer than those on mirror.centos.org)? HELP?
