Stouts.hostname

Ansible role for manage the hostname

Variables

The role variables and default values.

hostname_enabled: yes                       # Enable module
hostname_hostname: "{{inventory_hostname}}" # Set hostname
hostname_hostname_short: "{{hostname_hostname.split('.')[:-1]|join('.')}}" # Set short hostname

Requirements

If /etc/hostname has not already been created by the installer (e.g. a debootstrap system), AND you have already set an unusually restrictive umask, then /etc/hostname could be created with unusually restrictive permissions. Try not to do that.

This would probably only cause obscure, unusual (difficult to troubleshoot :) problems. /etc/hostname is only expected to be used by privileged software at boot time. Most other software should query the kernel value which the boot software set up, i.e. gethostname().

This is a limitation in the Ansible hostname module (as of v2.3.1). It does not enforce standard permissions for /etc/hostname. We don't try to set permissions ourself because some distributions use a different config file than /etc/hostname.
