For setups having limitations with open ports, such as in some cases PoD, xproofd provides the
possibility to serve the files produced during running via the same port. This was implemented
by starting a rootd process upon an incoming request for a file. The use of xrootd for this
purpose was not possible with earlier versions of XRootD (up to 3) because the file serving
protocol was not available as separate plug-in.
This patch enables the use of xrootd for this purpose and deprecates the use of rootd .
