FWIW, an approach that will probably save you a lot of rebasing work in
the future would be to rip out the readahead bits from that tree and put
it into a repository of it own. It's a standalone tool that just
happened to live in the systemd repo in the past. Some of the helper
functions would need to be copied over as well, but that should be

That way, you can even accept patches from other people and roll your
own releases etc.
