are hard link necessary ?

[MaxiReglisse]

when src and dest are not on the same device, the hard link creation fails.
in roles/georchestra/tasks/nativelibs.yml, we have :

• name: symlink gdal.jar to tomcat shared dir
  file: src=/usr/share/java/gdal.jar dest={{ tomcat_basedir }}/georchestra/shared/gdal.jar state=link
• name: hardlink gdal.jar to geoserver libdir
  file: src=/usr/share/java/gdal.jar dest={{ tomcat_basedir }}/geoserver/webapps/geoserver/WEB-INF/lib/gdal.jar state=hard
  it fails with this message :
  TASK: [georchestra | hardlink gdal.jar to geoserver libdir] *******************
  failed: [georchestra-ppd] => {"failed": true, "path": "/opt/tomcat/geoserver/webapps/geoserver/WEB-INF/lib/gdal.jar", "state": "absent"}
  msg: Error while linking: [Errno 18] Invalid cross-device link
  FATAL: all hosts have already failed -- aborting

question : is hard link necessary ?

I dont remember the details, but iirc a symlink wasnt enough for geoserver to work with gdal.
