[systemd-devel] /usr/lib/systemd/*.wants vs. Wants in unit definition

[Andrei Borzenkov]

What is advantage in having static *.wants etc directories in
/usr/lib/systemd vs. Wants etc directives directly in unit definition?
They complicate troubleshooting (you no more have complete definition
by looking just at unit source), they complicate building (extra steps
to install them); what are they good for?

This is precisely about static links in /usr/lib, not about admin
overrides in /etc.
