You can now use the READONLY_AFTER_INIT macro when declaring a variable and we will put it in a special ".ro_after_init" section in the kernel. Data in that section remains writable during the boot and init process, and is then marked read-only just before launching the SystemServer. This is based on an idea from the Linux kernel. :^)
