as I belive levels 5 and 6 are reserved for reboot and shutdown. the shutdown command I always need to type 10 times so I intended to alias the command then found that SuSe had saved me the job with restart and halt commands installed in /sbin
Not quite runlevel 5 on Redhat runs X!
man init will tell you that
Runlevels 0, 1, and 6 are reserved. Runlevel 0 is used to halt the system, runlevel 6 is used to reboot the system, and runlevel 1 is used to get the system down into single user mode.
btw if your x86 box is in runlevel 0 then it is switched off but on some architectures it means the machine is actually in a system maintenance mode but I have only ever seen this once myself on some very strange hardware and may now be a nice legacy from the olden days of Unix or on very odd computers.
