In my case I could login with the initial install but I rsync'd everything over while preserving ownership and permissions to another RAID partition and booted from that.was fine before. The problem is that you are kicked out the second you login and the problem was SELINUX for some reason (perhaps it noticed something strange when it was moved to the new partition)
login: pam_unix(login:session): session opened for user root by LOGIN(uid=0)
login: ROOT LOGIN ON tty1
pam_unix(login:session): session closed for user root
#in my case the issue was selinux so disable it
