[Solved] Raspberry Pi USB Boot

[clix]

Basically I have code in init.d to check at boottime that a certain memory pen is plugged in. Once I see that it works, I'll configure it to shutdown again if the pen is not detected. Unfortuantely it won't work. I have made it executable and tested it with bash usbboot start, when it works then, but still it doesn't work at boot. I think it even causes two of the "Starting this..." lines near the end to merge into one.

Code: Select all

#!/bin/bash
# /etc/init.d/usbboot
 
### BEGIN INIT INFO
# Provides:             USB Secure Booting
# Required-Start:       $remote_fs $syslog
# Required-Stop:        $remote_fs $syslog
# Default-Start         2 3 4 5
# Default-Stop:         0 1 6
#END INIT INFO
 
 
id="USB ID HERE"
 
case "$1" in
 start)
  if [ -z 'lsusb | grep "$id"' ]
  then
        echo "USB Key Not Found"
  else
        echo "USB Key Found"
  fi
  ;;
 stop)
  ;;
 *)
  echo "Usage /etc/init.d/usbboot {start|stop}"
  exit 1
  ;;
esac
 
exit 0

Try using blkid /dev/sda.

You can also use those blkids in your /etc/fstab to ensure that the wrong USB pen drive can't be mounted.

Solved. Needed update-rc.d to actually run it. Thanks for the suggestion Dougie, I'll try that out if I have time.
