Why would you need to update the FIS dir? After all, the skip regions don't change. I was thinking of the following method: - take the new kernel, check the size - if it's larger thab 1 MB, check whether mtd has a Kernel1 and Kernel2 partition. a) Take the size of Kernel1 from /proc/mtd (-16 byte for the header), split the kernel and write it to Kernel1 and the rest to Kernel2. b) Write the kernel to Kernel - write the ramdisk to Ramdisk > > Probably, we have sufficient agreement to move one. > > I think we do, but I'll try and get to IRC when you're there in case > there is anything else we need to clarify.
