Hi,
What I'd recommend is the following in your puppet manifest just
before the template() call to your file :
$fqdn = downcase($::fqdn)
...and that's it. You will need to puppetlabs-stdlib module.
The other solution is to use ruby inside your erb template, with this
as the first line of the file for example :
<% fqdn = scope.lookupvar('::fqdn').downcase -%>
Then use "fqdn" (the local ruby variable) instead of "@fqdn" (the
puppet variable) in your <%= fqdn %>.
