Could you please expand on your chain of reasoning here?  grub-mkconfig
exiting non-zero is absolutely an error as far as I'm concerned - it
might for instance mean that it was unable to generate a
syntactically-correct configuration file - and we should find out why
that's happening (for instance, by looking through the error output of
"sh -x /usr/sbin/grub-mkconfig >/dev/null").
