[Pulp-list] [Pulp-dev] Documentation Systemd clarification?

Tue Apr 2 21:33:30 UTC 2019

I updated the path on the docs as you identified. Also, we are considering
linking to the ansible-pulp templates directly since those contain all 3 of
the service definitions we need. I'm hoping to fix this tomorrow:
https://pulp.plan.io/issues/4629#note-4  Feedback on what we should do is
welcome.

Let us know if you run into more issues. Thanks!
