Description Fred van Zwieten 2016-09-24 07:34:29 UTC

Description of problem:
wrong sequence of commands and checks in 4.3

Version-Release number of selected component (if applicable):
Director Installation and Usage, par 4.3 Setting the hostname for the system

How reproducible:
Installed RHEL7.2 from ISO and gave it a fqdn in anaconda - network. Then, the command "hostname" works, but "hostname -f" not. After doing the hostnamectl commands in 4.3 "hostname -f" still does not work. Only after adding the fqdn to /etc/hosts as explained in the last bit of 4.3 "hostname -f" works.

Steps to Reproduce:
1.
2.
3.

Actual results:


Expected results:


Additional info:
This is hugely confusing for a first time admin. Suggest to specify the /etc/hosts modification bits first and all the other stuff after that.

Comment 1 Dan Macpherson 2018-03-19 11:05:31 UTC

Scoping old bug.

So the "hostname -f" command in this case is meant to check if the FQDN hostname is set. If it results in an error, that means the full hostname isn't set. So it acts as a test.

The wording has now been clarified: "f either commands do not report the correct hostname or report an error, use hostnamectl to set a hostname:"

Closing this BZ, but if further changes are required please let us know.
