Which, in turn, is implemented using (2): current libblkid (from util-linux)
looks into /dev/disk/by-uuid/ first and falls back to partition scanning if
that directory is not present.

The same is true for modern initramfs too - like dracut for example (which
is currently the only real choice for initramfs generator, and which may
produce either universal or specific initramfs images).
