And that would be maintained automatically even +if you just remove the include lines for other modules you could +use code like below, a sample /etc/motd would be: + +
+Puppet modules on this server:
+
+    -- Apache
+    -- MySQL
+
+ +Local sysadmins can also append to the file by just editing /etc/motd.local +their changes will be incorporated into the puppet managed motd. + +
+# class to setup basic motd, include on all nodes
+class motd {
+   include concat::setup
+   $motd = "/etc/motd"
+
+   concat{$motd,
+      owner => root,
+      group => root,
+      mode  => 644
+   }
+
+   concat::fragment{"motd_header":
+      target => $motd,
+      content => "\nPuppet modules on this server:\n\n",
+      order   => 01,
+   }
+
+   # local users on the machine can append to motd by just creating
+   # /etc/motd.local
+   concat::fragment{"motd_local":
+      target => $motd,
+      ensure  => "/etc/motd.local",
+      order   => 15
+   }
+}
+
+# used by other modules to register themselves in the motd
+define motd::register($content="", $order=10) {
+   if $content == "" {
+      $body = $name
+   } else {
+      $body = $content
+   }
+
+   concat::fragment{"motd_fragment_$name":
+      target  => "/etc/motd",
+      content => "    -- $body\n"
+   }
+}
+
+# a sample apache module
+class apache {
+   include apache::install, apache::config, apache::service
+
+   motd::register{"Apache": }
+}
+
+ +Known Issues: +------------- +* In 0.24.8 you will see inintended notifies, if you build a file + in a run, the next run will also see it as changed. This is due + to how 0.24.8 does the purging of unhandled files, this is improved + in 0.25.x and we cannot work around it in our code. + +Contributors: +------------- +**Paul Elliot** + + * Provided 0.24.8 support, shell warnings and empty file creation support. + +**Chad Netzer** + + * Various patches to improve safety of file operations + * Symlink support + +**David Schmitt** + + * Patch to remove hard coded paths relying on OS path + * Patch to use file{} to copy the resulting file to the final destination. This means Puppet client will show diffs and that hopefully we can change file ownerships now + +Contact: +-------- +You can contact me on rip@devco.net or follow my blog at http://www.devco.net I am also on twitter as ripienaar -- cgit v1.2.1
