Thorsten Glaser started yesterday with the implementation of the FreeWRT configuration filesystem. The specification of the filesystem is here. The main goal of fwcf is to enable a reliable update for the FreeWRT distribution. The complete /etc directory will be saved compressed in a separate flash partition and so can survive a complete update, including the linux kernel. FreeWRT is moving to a complete /etc based configuration. This is a common method to configure Linux-based systems and is non-proprietary. It is very similar to the nvram concept, but it does allow more than key-value pairs to be saved.
