It doesn't reserve 64kB. It doesn't really reserve anything at all. There can be as little as zero bytes of free space in the kernel mtd partition. The point is to pack it in as tightly as possible, leaving more space for the rootfs. I didn't think that field-upgradability by replacing only the contents of the kernel mtd partition was a design goal. Considering that it's likely that a kernel upgrade will also require a /lib/modules upgrade, I'm not sure it's even worthwhile to make it a design goal. Field- upgradability is addressed by sysupgrade, which is able to replace the entire firmware image (including the kernel and rootfs, with /lib/modules) while retaining configuration files and other files marked to be saved through the upgrade. _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
