Actually, it makes a *new* file when packing, and then unlinks the old
file and re-links the copy under its name after finishing the pack
successfully.  If you are looking to "spread the love" across multiple
partitions, you can symlink the original file into a directory on
another drive / partition, and then do the pack there.  One the pack
completes, you can move or copy the packed version back to the original
directory.

To do the pack in the temporary directory, something like the following
Python script should work::

  #!/path/to/your/python
  import time
  from ZODB.FileStorage import FileStorage
  to_pack = FileStorage('/mnt/space/packing/Data.fs')
  when = time.time() - (7 * 86400) # one week ago
  to_pack.pack(when)
