Title: Installing Red Hat Satellite

Describe the issue:
Step 6: "Run the following commands to configure the firewall to limit elasticsearch to foreman and katello users and make these rules persistent during reboots: " modifies firewall in such a way, that elasticsearch (on port 9200) can get connections from processes owned by foreman or katello. While during installation, katello-install script runs a check:

/bin/bash /usr/share/katello-installer/modules/service_wait/bin/service-wait elasticsearch start

under root user that tests that port accessibility (wget and curl against http://localhost:9200 are invoked).

Following installation manual, this check would fail with error:

 Could not start Service[elasticsearch]: Execution of '/usr/share/katello-installer/modules/service_wait/bin/service-wait elasticsearch start' returned 5: Starting elasticsearch (via systemctl):  [  OK  ]

(installation will succeed, just the error will appear what's confusing for an end user)


Suggestions for improvement:
Add there a rule allowing root to access the port. I.e.:

- s/to foreman and katello users/to root, foreman and katello users/
- add line:

iptables -A OUTPUT -o lo -p tcp -m tcp --dport 9200 -m owner --uid-owner root -j ACCEPT \
&&

to the box with commands (before "-j DROP" line)


Additional information:
I am curious why installations (with default firewall set and strictly following manual) could ever succeed without hitting this error. I installed Sat6 many times and hit this for the first time - on RHEL7 installed from iso with few packages updated.
