systemd-readahead is just trying to pre-cache stuff into memory so boot
time is faster. I'm not sure eaxctly what's going on here but that
message is typical of having a loop in your symbolic links (which can
easily happen with relative links).

I'm not quite sure what *exactly* is going on, but it looks like maybe
dracut temp files didn't get cleaned up properly and that they contain
such a loop. I bet you can just rm -rf /var/tmp/dracut.fP4yj1.
