# Fact: domain
#
# Purpose:
# Return the host's primary DNS domain name.
#
# Resolution:
# On UNIX (excluding Darwin), first try and use the hostname fact,
# which uses the `hostname` system command, and then parse the output
# of that.
# Failing that, it tries the `dnsdomainname` system command.
# Failing that, it uses `/etc/resolv.conf` and takes the domain from that, or as
# a final resort, the search from that.
# Otherwise returns `nil`.
#
# On Windows uses the win32ole gem and winmgmts to get the DNSDomain value
# from the Win32 networking stack.
#
# Caveats:
#
Facter.add(:domain) do
setcode do
# Get the domain from various sources; the order of these
# steps is important
# In some OS 'hostname -f' will change the hostname to '-f'
# We know that Solaris and HP-UX exhibit this behavior
# On good OS, 'hostname -f' will return the FQDN which is preferable
# Due to dangerous behavior of 'hostname -f' on old OS, we will explicitly opt-in
# 'hostname -f' --hkenney May 9, 2012
