Thanks for having a look. Yes, it looks appallingly complicated.
Sure, if I knew there was a file to write, and I knew where to write
it, I could do it in the "pre" script. But since I have no idea how the
actual backup is performed and how the "backup_label" file is going to
be saved, I thought it best to return the information to the caller and
persist it somewhere, and only the "post" script can actually return the
information.
