error: unpacking of archive failed on file /usr/share/foreman/public: cpio: rename

This error is caused by following the instructions on this link and then updating foreman via yum.
http://theforeman.org/projects/foreman/wiki/Setting_up_Nginx_+_Passenger_

The solution is simple, leave the default symlink /usr/share/foreman/public alone, but that breaks Nginx which doesn't like the symlink as a root folder.

So the work around (for me) to upgrade foreman via yum was
1. Backup old public folder (just in case).
mv /usr/share/foreman/public /usr/share/foreman/public.<version>
2. Re-create the symlink
ln -s /var/lib/foreman/public /usr/share/foreman/public
3. Remove any failed symlinks from the RPM install.
rm /usr/share/foreman/public\;50d7629d
4. Perform the RPM update
yum update foreman
5. Revert the public folder back for Nginx (as per the instructions in the above link)
rm /usr/share/foreman/public
cp -rp /var/lib/forman/public /usr/share/foreman/
6. Restart your services
service nginx restart
service foreman restart

Maybe there is a way to make Nginx operate happily from a symlink rootdir, if so then someone please update the document in the link above.
