I was just looking at that and thinking the same thing. Nothing is
really forcing rpcbind to load the way things are specified right now.
If a service really requires another service to operate, it should say
that. There is no problem doing that via a target, but then the
target still needs to pull it in.
There seems a general tendency in systemd to express dependencies as
"after" instead of "requires." That is fine if the service doesn't
really require something else, but if there really is a true
dependency then it just causes problems when somebody doesn't notice
and fails to enable the other unit.
