2483585 - Installation of HANA Cockpit 2.0 fails

The installation of HANA 2.0 cockpit fails with errors like 
"...cannot extract sapjvm_8/COPYRIGHT: cannot open /hana/shared/H52/xs/sapjvm_8/COPYRIGHT for writing: Permission denied"

It seems that the subdirectories in .../xs are being created with owner root and all entries are being written with the <sid>adm.
Even when trying an update, the directories are cleared and recreated with this ownership.

The directory structure looks as follows:
..:/hana/shared/S11 # ls -ltra /hana/shared/S11/xs
