External Libraries and Dependencies

The external libraries and dependencies required to run DIRAC Agents, Services, and Clients are contained in the DIRACOS. package for Python 2.7 installations, and in the DIRACOS2 package for Python 3 installations.

The default version of DIRACOS to be used with a given version of DIRAC is defined in the DIRAC/releases.cfg file. It can be overwritten with the --dirac-os-version flag for the dirac-install command. The documentation for creating a DIRACOS release or an extension of DIRACOS can be found in its own documentation.
