+  * etc/init.d/noosfero: forward fix for the Lenny → Squeeze upgrade. In
+    Squeeze, `rails` is an empty package that depends on rails-ruby1.8, but
+    rails-ruby1.8 is only unpacked *after* noosfero prerm runs. This way, the
+    initscript must be able to stop the services without any of the Rails
+    libraries available.
