i got this error using postfix:📡
Error: Could not retrieve catalog from remote server: Error 400 on
SERVER: Cannot reassign variable valid_fqdn at
/etc/puppet/modules/postfix/manifests/satellite.pp:32 …
reassigning a variable within a given scope doesn't work in puppet
see https://docs.puppetlabs.com/puppet/latest/reference/lang_variables.html#no-reassignment
i still think overriding $::fqdn is not a good idea, but for now,
i just want to get this class working again.
