[systemd-devel] readhead - systemd vs. readahead

[Andrey Borzenkov]

It seems that readahead sources already include systemd unit
configuration. I have readahead 1.5.7 and have here:

/lib/systemd/system/default.target.wants/readahead-collect.service
/lib/systemd/system/default.target.wants/readahead-replay.service
/lib/systemd/system/readahead-collect.service
/lib/systemd/system/readahead-replay.service
/lib/systemd/system/readahead-sort.service

What is relation of readahead services and systemd services? From
names they seem to be identical.
