Preventing non-root users from transferring root owned files

[rcorujo]

Thanks for your response Wayne.

The problem is that we are using SystemImager on our
Linux clusters and the SystemImager scripts do not
invoke rsync with ssh, so a daemon must be running as
root.

I have sent mail to the SystemImager mailing list.

Thank you.
