The following just fails:

% sudo grub-install --boot-directory=/boot --target=mipsel-loongson
--modules="ehci ohci usb_keyboard" --disk-module=pata --recheck
/usr/bin/grub-mkimage: error: cannot open
`grub-core/kern/disk.c:196:.mod': No such file or directory.

I just compiled/installed grub from git checksum

I suppose I better wait, so that I can provide the right output dump.
