[CentOS] CentOS 6 is a bear

here is just  a small sample of the errors in the messages log after 
initial boot.......
I think there is a bug with the video, something to do with grub 
according to peeps on the net.
I want to get rid of abrtd but the computer will never start again if I 
do..which does not make sense.
errors with network manager, gtk warngings, selinux has 5 things it 
wants to stop from running..
this is all at a first boot and second boot...
welcome to centos 6

these here literally make a hundred or so appearances in different forms
