Yes, that was exactly it, thank you.
For posterity, it works with this in site.pp (3.7.2 master/agent):
if $::devstyle and str2bool($::devstyle) and $::cluster and 'dev' == $::cluster
{
File {
replace => false,
}
notify { 'devstyle':
message => 'Not managing file contents, devstyle=true.',
}
}
And this in the inventory module:
if 'dev' == $::cluster {
$dscontents = "devstyle=true\n"
}
else {
$dscontents = "devstyle=false\n"
}
file { '/etc/facter/facts.d/devstyle.txt':
content => $dscontents,
}
Any developer wanting a real agent run on their pet host will remove that file
and have a production-style agent run.
I will flatter myself by thinking that other people might also run into this.
In that spirit I filed DOCUMENT-336 for a minor touchup.
https://tickets.puppetlabs.com/browse/DOCUMENT-336
Also for the next person to happen across this thread, there's a warning if the
file is a symlink or something else while this behaviour applies:
$ ls -ld /tmp/this
lrwxrwxrwx 1 cwood cwood 4 May 1 10:48 /tmp/this -> that
$ cat /tmp/z.pp
file { '/tmp/this':
ensure => present,
content => "this file has a string in it\n",
# replace => false,
}
$ puppet apply /tmp/z.pp
Notice: Compiled catalog for cwl in environment production in 0.07 seconds
Warning: /Stage[main]/Main/File[/tmp/this]: Ensure set to :present but file
type is link so no content will be synced
Notice: Finished catalog run in 0.10 seconds
