I feel a bit confused about the exact syntax for the grub.conf file. Did we cover if there are any specific rules for spacing or line breaks?

This seems similar to the practice question we did about modifying kernel parameters in grub.conf. I think I can apply that knowledge here.

I remember we discussed the kmcrl parameter in class, but I'm not entirely sure what it specifically does.
