After a week of skiing :-) I rejoined the project and noticed a couple of new lines in the console output.
These lines do not appear in the stderr.txt.
Is it just an info/a new test or a signal for an upcoming error?

/bin/cp: `/cvmfs/grid.cern.ch/vc/bin/gfal-copy´ and `/usr/bin/gfal-copy´ are the same file
/bin/cp: `/cvmfs/grid.cern.ch/vc/bin/gfal-rm´ and `/usr/bin/gfal-rm´ are the same file
/bin/cp: `/cvmfs/grid.cern.ch/vc/bin/boinc-proxy´ and `/usr/bin/boinc-proxy´ are the same file
/bin/cp: `/cvmfs/grid.cern.ch/vc/bin/boinc-shutdown´ and `/usr/bin/boinc-shutdown´ are the same file
/bin/cp: `/cvmfs/grid.cern.ch/vc/bin/dumbq-logcat´ and `/usr/bin/dumbq-logcat´ are the same file

It is just noise relating to a small miss-match between the code and image. I am working on new images in the dev project.
