Consider, you are not sure what kexec has been setup to do (maybe
some other admin has something setup to take a crash dump etc). You
do not want to destroy this setup, so you do kexec -q
Think being able to query the pending kexec is very usefull. Also
using an rc means that scripts can use it too.
