title: busybox start init script after bootup
body: <p>i am running an embedded linux device with busybox. after boot i want to start the ppp connection and do other things. i want to run it when everything else has finished and the system is up.</p>
  
  <p>my inittab looks like:</p>
  
  <pre><code>::sysinit:/bin/sh /etc/rc.d/rc.sysinit
  ::once:/bin/sh /flash/scripts/init.sh
  ::respawn:/sbin/getty -L ttyS0 115200 vt100
  </code></pre>
  
  <p>the script is executed and pppd get started but it fails. if i run the command manually after bootup, there is no problem at all. so i thought maybe its the runlevel?</p>
