Today in class, the teacher asked us to say different ways to shutdown/reboot,etc. the system. I said "poweroff" and I though that it was probably actually a symbolic link to "shutdown" or "halt".
We are using Ubuntu 12.04 and when I checked it turned out to be a link to "reboot" which kind of surprised me. How does that make sense?
In my Raspberry Pi running Debian I get: /sbin/poweroff: symbolic link to 'halt'
EDIT: I don't see how my question is answered there.It mentions that when forcing shutdown poweroff invokes the reboot syscall, but doesn't answer why it is linked to reboot(1)
