The problem was that no one worked on the readahead tool. Regardless
of what repository it lived in. My understanding is that
systemd-readahead was the best tool out there, so anyone could still
resurrect that if they want to (but my understanding is that there are
no one with both the interest and the opportunity to work in it a the
moment).
