Ensure that the status returns 0 instead of the last shell command result, otherwise the calling script can not properly detect the status of pid.

--Shell-script--
functions This file contains functions to be used by most or all
shell scripts in the /etc/init.d directory.
NOTE: The pidofproc () doesn't support the process which is a script unless
the pidof supports "-x" option. If you want to use it for such a
process:
1) If there is no "pidof -x", replace the "pidof $1" with another
command like(for core-image-minimal):
ps | awk '/'"$1"'/ {print $1}'
Or
2) If there is "pidof -x", replace "pidof" with "pidof -x".
pidofproc - print the pid of a process
$1: the name of the process
pidofproc () {
# pidof output null when no program is running, so no "2>/dev/null".
