Testing an Globus Free OSG-Software (From EPEL(-testing))

As you may or may not know, there is a massive globus update pending in EPEL that will update globus to the version the OSG distributes.  What this means is much less work for the osg-software team since we will not have to build and support our own builds of globus.Testing the globus from EPEL while installing some packages from osg repos is not a trivial matter.<ol><li>Disable the priority of the OSG repo</li><li>Exclude globus and related packages that are already in EPEL from the osg repo.</li></ol>Below is my final file /etc/yum.repos.d/osg.repo Notice the many excludes in the file, the list may not be complete.Installation is just:<pre>yum install osg-client-condor –enablerepo=epel-testing</pre>UPDATE!!!!Testing Resultsvery good!I ran 3 tests, all completely successful. 1. globus-job-run against a rpm CE.<pre>$ globus-job-run pf-grid.unl.edu/jobmanager-fork /bin/sh -c “id”uid=1761(hcc) gid=4001(grid) groups=4001(grid)</pre>2. Condor-G submissionCondor-G Submission worked without problems.  The submission file is below: 3. And globus-url-copy worked:<pre>$ globus-url-copy gsiftp://pf-grid.unl.edu/etc/hosts ./hosts</pre>
