The feeling I get from the discussion you linked above and the discussion here is that because user can be an idiot and delete files at random, we should move back to the 80s and store files like on the casette tapes, at random offset. User can also delete kernel image and yet, we store it on the filesystem. Maybe we should also store the kernel image at another raw offset ... and hey, maybe we should ditch filesystem altogether, just tar everything up and store it at yet another offset, since user might delete files at random, just imaging he'd delete libc ... -- Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
