Hmm.  initdb knows nothing about systemd unit files, and would not
have the permissions to modify them even if it did know, since it
doesn't run as root.

This isn't really a matter for the core Postgres distribution, because not
one of the files you mention is part of the core Postgres distribution.
You could take it up with whoever produces the package you are using.

My guess is that the packager will say that manual invocation of initdb
isn't the right way in their package and you should use some wrapper
script instead --- in which case you could move on to why the wrapper
script isn't adequately documented or how it lacks some functionality
you need.  But this list isn't well positioned to help you.
