No, in that case /mnt/motd/* has to be on the machine that builds the
catalog, as that's where all Puppet functions will be evaluated. Since you
are using a puppetmaster for that purpose, that's where the files need to
be. I'd probably write it like this, though:
$a = file("/mnt/motd/motd-${::hostname}",'/dev/null')
file {$config_file:
ensure => 'file',
owner => 'root',
group => 'root',
mode => '0644',
content => $a ? { '' => template($template), default => $a }
}
