I've been working with various Unices for 15 years now and it has only been this thread that brought my attention to the evils of 'reboot'. I've always typed 'reboot' since I was worried that I'd accidentally type 'shutdown -R now' by mistake (or some similar typo) which would shutdown the box instead of reboot it, and then I'd need to spend the next 4 hours of my life traveling to a data centre. And 'reboot' was fewer letters to type. Why would an operating system have an unclean shutdown command at all? It would be more direct to just have a 'rand' command which writes random data to 5 random sectors on disk... :-) And surely if a process is stuck, it should be killed individually? Perhaps if this command is really needed it could be buried under "reboot -f" or something like that. For what it is worth, OSX does a clean graceful reboot with 'reboot'.
