So I think somewhere early in the sequence of init 5 scripts something else turns on the splash screen if it wasn't already on from boot. I might have even fixed that already in my other Centos 6.5 but forgot what I fixed. I'm not sure (the startup on the one that might have that fixed is ripped up at the moment as I experiment to improve some display issues).
UNLESS you edit the config file that is used TO MAKE the /boot/gurb/grub.conf
and that is /etc/grub.conf
As mentioned earlier in this thread, the Centos 6.5 installer installed legacy grub on my systems not the current grub. I don't know which the OP has.
In legacy grub, /etc/grub.conf is just a symlink to /boot/grub/grub.conf. It is not the config file used to make /boot/gurb/grub.conf
In legacy grub, I don't know a way to avoid needing to re edit the kernel line in grub.conf after each update of the kernel.
