/sbin/consoletype should have a 0755 mode.
 
Insert the #1 installation CD (any, even back a few releases should work fine),
or other (e.g. live) CD, and boot "linux rescue"
 
When possible, do ls -l on /sbin/consoletype on your main (root) disk (r.g. ls
-l /mnt/sysimage/sbin/consoletype)
 
What's the mode?

I hava not CentOS's CD,but i had made a live-usb of debian5,when i entered
its rescue mode ,i found it need a CD,then i entered a shell ,but i cannot find
the fs,i donnot know how i can mount the fs,because it hadnot mount command,any
idea?
I find CentOS had some problem:sometime there is a fs error,all icons cannot
load ,then i tried log in the shell,it said there was fs error,however i
rebooted the system ,everything was ok!
In all those problem,i had not do any bad thing to the system.
