Mock 'Directory not empty' error during --clean

[Greg Trahair]

Hi Mike,

The directory is completely empty, and mock --init and mock --clean give
the same error.  Even a mock --no-clean --init gives the error.

The strange thing is that I can (as my unprivileged user) just run rmdir
/data/mock/dist-rhel5-greg with no problems, so permissions are not the
culprit.  SELinux is disabled.

I can recreate the problem every time I run mock --init, I have to rmdir
the buildroot before I can continue testing builds.

After a little testing, it seems that /data/mock being NFS is an issue,
as I just changed the buildroot back to /var/lib/mock and all seems ok.
Both /data/mock and /var/lib/mock are set 2775 root:mock.

I can't find any limitations of os.rmtree an nfs.

Regards,
Greg

It's hard to know without more data. The error is happening within 
os.rmtree.

Have a look at the remains that were not deleted. Is there anything 
unusual about them? Is it possible another process wrote files to 
directory during the clean operation? Does the problem repeat?
