The loader itself also has arguments.

You can easily modify the code.

Yes, there is. First of all the commands are quite trivial. Besides that, these commands are really the core of GRUB 2. The same commands are hardcoded into rescue mode as well. -- Marco _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
