regarding /dev/serial, this should be helpful for anyone wanting to set up netboot.
If you have a number of RPI's that netboot, the way that the common config.txt is segmented for each board is by using the '[serial number in hex]' section headers. Unfortunately, netboot also requires changing the BOOT_ORDER parameter in EEPROM, which requires access to /dev/mmcblk* and some way of generating the proper .bin format. So Linux is still needed for the initial setup.
