I am having second thoughts about running the 7260 from a SDcard. You get everything that I wanted by running it from a NFS root. My original motivation for running the card off a SDcard was that if I had my laptop on someone else's network then I would constantly be reconfiguring the board to adjust the new network. I am, right now learning how to run DHCP from my laptop to issue addresses on an network address on an obscure network address (172.28.1.0/255.255.0.0) with two network addresses bound to my ethernet NIC. With that I will be able to plug into anyone's hub and be able to have the 7260 NFS mount my laptop.
There are two reasons not to run the board from the SD card. First, by choosing the SD card option is mutually exclusive with the XDIO, which is really useful in embedded work. Secondly, the to run get the board to boot from the SD card you have to modify the boot ROM, which eliminates the RedBoot system. With RedBoot gone you have to do the same things you have to modify an initrd that gets installed to the SD card.
