Updated to add warning for updated kernel package, as some functionality doesn't function as desired when you're booted to a kernel that has upgraded (e.g., can't load modules for the booted kernel). I also changed the final call to yay to use exec so that the return code from yay is passed along to the caller of the wrapper script.

Updated to add powerpill support as well as adding config flags to enable/disable various functions.
