halt vs. reboot
Authored by: sheurich on Mar 08, '06 08:01:08PM

The difference between halt and reboot, which is a substantial difference, is that halt powers off the machine, while reboot restarts the machine. Halt is not equivalent to 'reboot -q' and in fact both halt and reboot respect the '-q' flag.

halt vs. reboot
Authored by: Zeitkind on Mar 09, '06 12:04:18AM

Of course halt powers off the machine - but what is the difference between restart from scratch and a power cycle - regarding fsck? Apple decided to power off if root fs is modified - but why? Rebooting does the same as halt except erasing the RAM and other non static memory. If you flash a firmware, OK, no question, but if you fsck? The drives are called quite late in the boot process of OF and they also do a bus-reset while rebooting. So why the halt command instead of reboot?
