Hi Brian,
Sorry about the delay in responding. Unfortunately eval didn't work or at
least fqdn does not output the value I set it to in test_values.
I am just going to rework my testing to dump a file into
/etc/facter/facts.d and remove it after use. Not ideal but it works with
the least amount of fussing around. I would have loved to get the
commandline option working as I would not have to add and remove files when
I am testing things out.
Thanks,
Peter.
