Description

The pulp ostree publisher uses libostree pull-local which by nature will hard link files instead of copying them. However, the AtomicDirectoryPublishStep.process_main() in pulp uses shutil.copytree() instead of at least attempting to move the working-directory to the master/<timestamp> location. The result is, the ostree plugin pull-local creates an ostree repository using hard links but the copy operation creates a copy. Given the size of ostree repositories, this uses a ton of disk.

THIS NEEDS TO BE FIXED IN PLATFORM.

Should be doing something like this:

try:
     rename()
except OSError as e:
    if e.errno == errno.EXDEV:
        copytree()
    else:
        raise
