I'm getting an some kind of error at the VGA console when I make a configuration file for grub (at least I think it's an error), with
grub-mkconfig -o /boot/grub/grub.cfg
I tried to redirect stderr and stdout into a file named ~/grub_error like this:
grub-mkconfig -o /boot/grub/grub.cfg 2>&1 ~/grub_error
However, what I though to be an error, still printed to the screen (~/grub_error had stdout redirected to it, so I don't think I made a syntax error).
I also noticed that when I run
grub-mkconfig in a terminal in an X session, the "error" that shows up on the VGA console doesn't show up. Is there something else I should be redirecting, because the error seemed pretty serious, something along the lines of "...could lead to file system corruption". It may be worth noting that i'm using a BIOS machine with GPT, so I have a bios_boot partition, and the error said something about /dev/sda1 (my bios_boot partition) not having and ext4 file system (which it doesn't and shouldn't).
