Please try not to introduce that padding, it's quite a big impact on all devices while only very few (wifi-only device) really need that change. Instead of wasting flash space by additional padding I'd rather want to see an OpenWrt-specific kernel-patch to allow a rw subpartition sitting inside an ro partition or just flatten the mtd partitioning. What I mean by flatteing is this: yout current approach: +-----------------------------+ | firmware | +--------+--------------------+ | $ rootfs | | kernel +------+-------------+ | $ rom | rootfs_data | +--------+------+-------------+ here rootfs_data inherigs the read-only from rootfs not being block- aligned. a better/flat approach would be: +-----------------------------+ | firmware | +--------+------+-------------+ | kernel $ rom | rootfs_data | +--------+------+-------------+ Now this would require major changes to our mtd-splitting subsystem which is quite a big amount of work...
