There's never a guarantee, but you can at least reduce your likelihood of failure. And seriously, having support to call an ioctl() in halt vs ldd across a static list of binaries and then cat'ing all of those files to /dev/null before running eject(1)? One of these feels like a hack, one of them feels like an incredibly gross hack ;) Jeremy -- upstart-devel mailing list upstart-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/upstart-devel
