If I understood correctly, the GRUB shell relies on device.map to translate
BIOS devices into kernel device files, and uses standard Un*x calls on /dev
to access the devices. Is that it?

IIRC, the kernel (at least, when that kernel is Linux) forwards read/write
calls to the target when the file is a symlink, but the same doesn't apply to
ioctl, so programs that rely on ioctl must be capable of resolving symlinks.

I believe a good solution could be to fix kernels to forward requests on
ioctl too, if that fixes the problem.

Is all this correct or did I miss something?
