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 :)
