Crash-only software: More than meets the eye:
Next time your Linux laptop crashes, pull out your watch (or your cell phone) and time how long it takes to boot up. More than likely, you're running a journaling file system, and not only did your system boot up quickly, but it didn't lose any data that you cared about. (Maybe you lost the last few bytes of your DHCP client's log file, darn.) Now, keep your timekeeping device of choice handy and execute a normal shutdown and reboot. More than likely, you will find that it took longer to reboot "normally" than it did to crash your system and recover it - and for no perceivable benefit.
