Might I suggest that there should be neither Pulp nor Katello init

which is confusing (witness OP) and can be difficult to manage. Keep
it simple -- starting Apache starts Pulp, so we already have a Pulp
init script. It's called "httpd" (and "mongod" and "qpidd").
That's a possibility too. The intention was to simplify things for
users; in theory it's easier to tell them to run one script (with pulp
in the name) instead of three.
But if telling people about the three feels better that might be the
right approach. That script already has problems in systemd, so removing
it entirely would make life easier than trying to find a way to replace it.
Alternatively, the *-service script suggested earlier might be the
compromise. It's outside of the systemd/initd infrastructure but still
available to those who care about it.
I like this approach. Having an init.d/systemd script/unit that just
aggregates other /true/ services has always felt wrong and (as Jay
mentioned) problematic. Most users will configure httpd, mongod and
qpidd to start automatically. Also, when users need to bounce one of
the services, it's usually to solve a particular issue that is related
to the service being restarted. Using pulp's current init.d script has
the unwanted side effect of bouncing the other services unnecessarily.
Another suggestion would be to symlink init.d/pulpd -> init.d/httpd.
Not sure it's necessary but does have a certain symmetry with the
symlink we create for the agent init.d/goferd -> init.d/pulp-agent. Not
convinced this is a good idea but thought I'd throw it out there.

I encountered one problem with Pulp init.d script:
When we start or stop Katello using

I believe that Pulp init.d script should not start or stop other
services.
It is valid scenario that I may want to stop just Pulp, but not Apache,
which should e.g. serve "Sorry we are in maintace" page.
If you want to have script which start/stop all services, which Pulp
use, you can steal:
/usr/bin/katello-service
from Katello (which we steal from Spacewalk).
May I kindly ask you to edit Pulp init.d script to start just Pulp?
The thing is, there is no Pulp outside of Apache. That script takes
care of
mongo, apache, and qpid. If you don't stop Apache, Pulp keeps running.
I'm confused at your maintenance page example though. If the issue is
that
Apache is started/stopped by Katello as well, how is that need met by us
removing Apache from that init.d script?
I'm open to suggestions. We've talked about a *-service type script,
but at
the end of the day that's going to be the same thing where Apache is
started/stopped/restarted to accomplish the Pulp notions of those
operations.
