Configuration File For Windows User

[FatherOfMachines]

I'm a windows user, and I'm not good at all with linux.

There are many configurations that are meaningful at robot level, like:

MAC address of ethernet interface
Name and PWD of default wireless network
Name and baud rate of the USB port for rosserial (AMA0, TTYUSB0, pippo)

What I'd like is a txt file in the boot partition.
At startup an SH script parse the txt file and update all the configuration files in the linux partitio.
FAT can be seen by windows, so i can plug the SD in my PC, edit the config.txt, plug the SD in the raspberry and quickly configure system level.
