            Bug ID: 1280529
           Summary: Document incorrectly suggests using FQDN in
                    /etc/hostname
           Product: Fedora Documentation
           Version: devel
         Component: networking-guide
          Assignee: swadeley at redhat.com
          Reporter: jkeating at j2solutions.net

Description of problem:
https://docs.fedoraproject.org/en-US/Fedora/23/html/Networking_Guide/ch-Configure_Host_Names.html#sec_Understanding_Host_Names

This section of the documentation recommends using a FQDN for the static
hostname, which is stored in /etc/hostname. However if one does that, uname -n
(to find the node name) will always return the FQDN. This has impact on
subsystems like python when determining the short name of the host. A better
solution is to use the shortname in /etc/hostname and supply a FQDN in
/etc/hosts.

Version-Release number of selected component (if applicable):
devel (shown as 23)


How reproducible:
Very

Steps to Reproduce:
1. Follow directions leading to FQDN in /etc/hostname
2. uname -n
3. hostname -s

Actual results:
FQDN shown as nodename, which does not match hostname -s

Expected results:
uname -n and hostname -s would both report the same short name, as defined in
/etc/hostname

Additional info:
The RHEL7 documentation also suffers from this defect.
