Why won't lsyncd start?

Question

Debian

I have debian 8.1 jessie
Installed lsyncd:

apt-get install lsyncd
mkdir /etc/lsyncd
mkdir /etc/lsyncd/lsyncd.d
touch /etc/lsyncd/lsyncd.conf.lua
touch /etc/lsyncd/lsyncd.d/srv1.conf.lua

lsyncd.conf.lua:

settings{
  logfile="/var/log/lsyncd/lsyncd.log",
  statusFile="/var/log/lsyncd/lsyncd.status",
}

local confdir = '/etc/lsyncd/lsyncd.d/'
local entries = readdir( confdir )

for name, isdir in pairs( entries ) do
    if not isdir then
        dofile( confdir .. name )
    end
end

srv1.conf.lua

sync{
  default.rsync,
  source="/home/user/src",
  target="/mnt/bakup"
}

when run from command line:

lsyncd /etc/lsyncd/lsyncd.conf.lua -pidfile /var/run/lsyncd.pid -logfile /var/log/lsyncd/lsyncd.log

everything is working fine.
and here is the command:
/etc/init.d/lsyncd start
or
service lsyncd start
does not start the daemon. what could be the problem?
