 16. If you can get past each of these steps, then your build farm system meets the minimum requirements.
 17. The official process can be kicked off by running `/home/farm/code/run_cron.sh --run-all`.  This will run the default build configuration, keep track of the git repository status, and upload the build results to the server.
 18. Once that command runs with no complaints, add it to the **farm** user crontab.  You can run it at whatever frequency you choose, I suggest 1 hour.  If a previous instantiation is still running, the script will detect the lockfile and exit so as not to step on each other.

+    #!/bin/bash
+    export PATH="/usr/local/bin:/sbin:/usr/sbin:$PATH"
+    $HOME/code/run_cron.sh --run-all $@

 
 ## Multiple build clients on one machine
 As mentioned above, you can start at step 9.  A second application must be filled out to put the appropriate data in the database because this is treated a separate BuildFarm client:
