Log message:

Dynamically link these /sbin daemons: dhcpleased, mountd, nfsd, pflogd, resolvd, slaacd, unwind.

The mitigation story is way better: syscalls are in a randomly located libc, and every syscall stub is randomly located inside that due to random relinking. As opposed to fixed offset inside a release binary. There is one known consequence: /usr nfs mounting must use statically configured IP addresses.
