-Disabling the Ubuntu repo cache if rsync is not allowed
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-During the build phase, a local Ubuntu package repository is fetched
-from upstream in order to be added to the OPNFV Fuel ISO and for parts
-of this process rsync is used.
-
-If neither of the two available methods for proxying rsync are
-available, the last resort is to turn off the caching of the Ubuntu
-packages in the build system. This is done by removing the
-"f_repobuild" from SUBDIRS in the beginning of
-the fuel/build/f_isoroot/Makefile.
-
-Note! Doing this will require the Fuel master node to have Internet
-access when installing the ISO artifact built as no Ubuntu package
-cache will be on the ISO!
