D-Link DNS-323 and Conceptronic CH3SNAS support integrated in installer

I finally had a chance today to test the patches Matt Palmer created to add D-Link DNS-323 support to the Debian installer. I tested the patches on a Conceptronic CH3SNAS which, from a hardware perspective, is a D-Link DNS-323 (rev B1). I noticed that the firmware image specifies a number for the vendor, so we have to generate different installer images for the D-Link DNS-323 and Conceptronic CH3SNAS. That was easy enough to do and I was able to install Debian without any problems.

The next steps are to write an installation guide and other documentation, and to improve the kernel (the power LED is blinking and cannot be changed, and fan control is missing).
