A followup to this discussion. Is there a more optimal way to ensure
the file (/etc/postfix/transport.db) is created by the exec and is
subscribed to the source file?
file { "/etc/postfix/transport":
source => "puppet:///private/etc/postfix/transport",
}
exec { "build_transport_index_for_mailman_if_it_doesnt_exist":
command => "postmap /etc/postfix/transport",
path => "/bin:/sbin:/usr/bin:/usr/sbin",
unless => "test -f /etc/postfix/transport.db",
}
exec { "rebuild_transport_index_for_mailman":
command => "postmap /etc/postfix/transport",
path => "/bin:/sbin:/usr/bin:/usr/sbin",
subscribe => File["/etc/postfix/transport"],
refreshonly => true,
}
Thanks for any hints.
