I'd say I'm too careless in understanding how grub2 message logging. I
see grub_error(...) and think it was logged to screen immediately
after that function returns, which is completely wrong.

The error message and number are staging in the buffer and it's up to
the module to use grub_print_error (...) to flush all pending messages
to the screen.  Nevertheless you could stack errors with push|pop,
which is extremely useful as grub2 could be stacked by modules ..

Glad to know one more good and flexible design of grub2. :)

Thanks,
Michael
