In popular RPM- and Debian-based Linux distributions with glibc 2.38,
libcrypt.so is now indeed installed in a separate package.
However, it appears that this package is critical and provides
dependency either for systemd or libc, which cannot be removed.
So, I don't see so far, how nginx is affected in practice.
