On most (all?) Linux systems, calling halt from a non-zero runlevel will invoke "shutdown -h now", but don't *ever* try that on another system. "telinit 0" is probably another synonym.
Just FYI halt on some systems will make the machine instantly poweroff, no umounting of disks nothing, Its a bit like pulling the power cord out of the back of the machine, just though I should let you know so no-one goes into work and trys it on any spare unix boxen to see what they do.
