Indeed, it's quite system dependent and possibly not even true by
default for the typical system nowadays. Since it's quite annoying
to end up with a non-bootable system though it still might be better
to be safe than sorry. Though we should adjust our error message and
support skipping this check.

Thanks for your bug report!
