Thanks. I've just looked at this one and it has "After=syslog.target
network.target auditd.service".

AIUI, "After=network.target" (and similarly "After=syslog.target") is
equivalent to having "Wants=network.service NetworkManager.service
<other_network_managers>" and "After=network.service
NetworkManager.service <other_network_managers>".

But "After=auditd.service" is clearly an example of an "After="
without a "Requires=" or a "Wants=". Thanks again.

PS: You'd expressed an desire for a dependency chain file in an
earlier email. "systemctl list-dependencies" shows you the current
dependency resolution. It's not what you were looking for but possibly
something of interest (it has modifiers like "--after" and
"--before").
