Cache consistency problem

[hurricup]

If something bad happened during installation process and bad data was stored in the cache folder (.tmp one), next time you'll try to install the same module - broken data will be installed.

To reproduce, you may install something, than go deep into .tmp dir and remove all files, keep only dirs structure. Try to install same module again - you'll get only dirs structure from the cache.

Possible solution: to make a filelist with md5 or smth for every file.
I'm unsure if this issue is for Librarian framework or librarian-puppet.
