The lesson is, "ps | grep blah" will find "grep blah" in the ps list:
(0) phreaque /home/keeling_ ps aux | grep acpid
root 10 0.0 0.0 0 0 ? S< Mar13 0:00 [kacpid]
root 2228 0.0 0.1 1572 568 ? Ss Mar13 0:00 /usr/sbin/acpid -c /etc/acpi/events -s /var/run/acpid.socket
keeling 27188 0.0 0.1 3692 640 pts/2 R+ 20:47 0:00 grep acpid
Note that last line. It has nothing to do with whether acpid is
actually running or not. Aka, noise.
