I don't see anything obviously forgotten or wrong, but there are a few
strange things:
1. You collect the same exported File resources twice in the same
class. I wouldn't have expected that to be a problem, but unusual code is
more likely to tickle bugs. I suspect that this is indeed where your
trouble lies.
2. You seem to be declaring relationships that for the most part
duplicate those that Puppet can normally be relied upon to create
automatically ("autodepends"). Specifically, if a file and its parent
directory are both under management, and no relationship is otherwise
declared between them, then Puppet will automatically manage the directory
before the file. Explicitly declaring the same relationships is not an
error, however.
3. You are declaring recursive directories without any 'source'
parameters. That probably does not mean what you think it means, because
in that case the recursiveness has no effect.
4. You declare 'force => true', which is only necessary to enable
clobbering existing directories, but the other parameters don't contain
anything that could make that needful.
5. You declare that File['/usr/local/puppet_host/list'] must be applied
before any of the exported Files tagged 'exported', but that does not
appear to be needful. Still, that's not erroneous.
I might write class test::server more like this:
class test::server {
file { [ '/usr/local/puppet_host',
'/usr/local/puppet_host/exported' ]:
ensure => directory,
mode => 750
}
file { '/usr/local/puppet_host/list':
mode => 440,
content => "List.\n",
}
File <<| tag == 'exported' |>> {
mode => 0644,
}
}
For explicit relationships, either declare them via the 'require' and/or
'before' metaparameters, or put chain operators between the declarations
above as needed.
