Description James Slagle 2017-08-17 12:39:43 UTC

When you install the generated katello-ca-consumer rpm from a satellite server, it sets the network.hostname-override to result of the "hostname -f" command.

If no fqdn or domain name is actually set on the system, then that command just returns "localhost".

When the system  is actually registered to satellite the host will be called localhost instead of the actual hostname (or short hostname if one is set). I actually have a set hostname on the system which could be used instead if not for the override fact being set:

[root@centos7 ~]# jq . /var/lib/rhsm/facts/facts.json | grep hostname
  "network.hostname": "centos7.localdomain",
  "network.hostname-override": "localhost",


Also, if you have 2 different systems that no fqdn set and you register them both to the same satellite, than only a single host is created in satellite called "localhost" and one registration just overwrites the other one.

Would it be possible to default to "hostname" if "hostname -f" returns localhost?

Should hosts created in satellite be overwriting one another if they only share the value of "localhost" for their fqdn?

The functionality to match the host against the hostname if it already exists is there on purpose, to make it possible to match provisioned host with the one registered with subscription manager.

Changing the component to installer, since that's where the katello-ca-consumer rpm is generated.
