Same problem with modules, actually. If you add a new module option to modules.conf and then go back to an older kernel your module won't load (here's where kaos pokes me with the rtfm stick). You can create a second entry in lilo.conf which refers to the same kernel image, but which doesn't have the rootflags option. - - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
