			==Creating Startup Service==

			To create the startup service without logging into the Pi, you can mount the SD card from Linux (or a Mac with FUSE or the ability to read ext4 filesystems) and modify the contents of the NON-BOOT partition of the SD card, which contains the Raspberry Pi file system.

			You put your startup script into <code>/sdcard/etc/init.d</code> and then you symlink that startup script into whichever run levels you'd like, with the prefix S02, which indicates this is a runtime level 2 or higher service. (The Raspberry Pis boot into runtime level 2 by default, and sshd starts in runtime level 2.)

			<pre>
			$ cd /sdcard/etc/init.d/
			$ ln -fs capture-wifi-data ../rc2.d/S02capture-wifi-data
			</pre>

			and optionally, what you would do on a heavy duty system that uses multiple runtime levels,

			<pre>
			ln -fs capture-wifi-data ../rc3.d/S02capture-wifi-data
			ln -fs capture-wifi-data ../rc4.d/S02capture-wifi-data
			ln -fs capture-wifi-data ../rc5.d/S02capture-wifi-data
			ln -fs capture-wifi-data ../rc6.d/S02capture-wifi-data
			</pre>
