Erm, ignore the part about global variables. Exporting them doesn't help:
for (var = context->prev->vars[i]; var; var = var->next)
{
if (var->type == GRUB_ENV_VAR_GLOBAL)
if (grub_env_set (var->name, var->value) != GRUB_ERR_NONE)
{
grub_env_context_close ();
return grub_errno;
}
}
So, we just preserve hooks ?
