Okay, granted nm will tell you when new syscall entry points get added... but you won't know about new syscall flags, new ioctls, new device nodes, new sysctls, new behavior, etc. Not saying you can't use nm as a backup sanity check, but it's not something I'd recommend relying on by default. Our userland is really not designed to run on older kernels.
