+
+Erm, /usr/{lib,bin} etc. are directories in the package and in the
+filesystem you link above so I'm not sure what you mean about "transform
+[them to] symlinks" in the statement above. There is no pre script that
+does anything to these folders.
+
+However, the /{lib,bin} etc folders *are* symlinks in the package. There
+is a pre-transaction lua script that creates the /usr/blah folders and
+the corresponding symlinks early because we cannot guarentee that
+filesystem will be the first package actually physically installed in
+the transaction and thus /bin or /lib etc. may be implicitly created as
+directories by other package installation in the same transaction. So
+the lua script just pre-empts what the package will do but it ensures it
+happens at the start of the transaction.
+
+I'm not sure if that answers your question or not because the comments
+in the spec file are quite clear about the purpose so they should have
+cleared up any confusion you may have had.
+
+So if I've not grasped what you are asking properly, please clarify and
+I'll try again :)
