grub-emu is broken since rev 2036

[Felix Zielcke]

Hi,

since revision 2036, i.e. Bean's command rewrite grub-emu is broken. On
every command you'll get `invalid arch independent ELF magic'.

Hi,

This is caused by the dynamic loading of commands. In normal.mod, it
scans command.lst and tries to load command on demand. However, the
modules on disk are pc booting, they can't be loaded by grub-emu. The
solution is to point the root device elsewhere with -r option, so that
command.lst won't be found.

But then, other things can't be found, like grub.cfg.

Can't we disable module loading altogether on grub-emu?  Or just silence
the warning there.

Hi,

The dynamic command loader can be separated in a module. In grub-emu,
we just don't use it.

Anyway, this issue is only temporary. After my patch to split the
normal mode, it will go away.

I suppose you mean separated to another .c file;  putting the dynamic loader
in a module is like... uhm :-)
