# The python hyrisecockpit module will be installed at the location Cockpit/venv/lib/python3.8/site-packages/hyrisecockpit. 
# In the installation process, all python files will be copied to this location. If we run the installed cockpit (hyrisecockpit module)
# the copied files are used. Because the process manager is part of the hyrisecockpit python module it needs to have an absolute path to the frontend. 
# The frontend is not part of the hyrisecockpit python module. So the process manager can't use a relative path hyrisecockpit/frontend because it runs 
# in Cockpit/venv/lib/python3.8/site-packages/hyrisecockpit and the frontend lies in Cockpit/hyrisecockpit/frontend. 
# That's the reason why we need to adjust the frontend relative path variable for the process manager in an absolute path variable.
