[systemd-devel] confusing message "systemd[1]: nss-lookup.target: Dependency Before=nss-lookup.target dropped"

[Ulrich Windl]

Hi!

I see the message
systemd[1]: nss-lookup.target: Dependency Before=nss-lookup.target dropped
several times, wondering:

Does it say "nss-lookup.target" has a dependency "Before=nss-lookup.target" that was dropped, or is the first argument simply the wrong unit being displayed? It's systemd 228 of SLES 12 SP4.

It's hard to believe a unit has a Before= dependency on itself.
Looking into the unit directly, I cannot see such a direct dependency.
Or is it "Artificial intelligence biting in its own tail"?

Regards,
Ulrich
